Carbon Fibres and Composite Material Free Sample for Students

According to Goodman et al. (2011), a composite material refers to a combination of two or more materials that are of different composition, physical property, and morphology. These materials are often combined on a microscopic scale. Depending on the constituent properties, composites are in many cases designed to (or â€Å"intending to†) producing materials with materials aimed at fulfilling specific mechanical, physical, or chemical requirements. As a result, Hofmann (2016)   points out that the use of composite materials have progressively increased for the past 40 years and have many uses in the automotive, aeronautic, medical, and naval fields among other industries. Consequently, different composite biomaterials have been tested and studied for use in the medical field and are often commercialized for their advantages of the traditional composite materials that were used before. In the medical field, most human tissues such as skin, bones, tendons, teeth, and ligament are composites made up of single constituents whose distribution, morphology, amount, and properties are the major determinants of the final behavior of the resulting organ or tissue according to Paknikar and Kumbhar (2015). The same study denotes that human-made composite materials can as well be used in making prostheses that are used to mimic these biological tissues with the aim of ensuring thy match their mechanical behavior and restore the mechanical functions of the body tissues that have been damaged. This paper presents the history, structure and synthesis, mechanical properties, possible uses, as well as pros and cons of the carbon-fiber-reinforced,   peek (CFR-PEEK) composite material whose use have been studied, tested, and proven fit for medical purposes. Carbon Fiber, a polymer that is also known as a graphite fiber, is a very strong material and light in weight. Though stiffer than steel, its light weight makes it suitable for use as a raw material in the manufacturing of other materials (Garry, 2013). The composite material was discovered back in 1879 by Edison Thomas. The scientist backed bamboo silvers and cotton threads at high temperature carbonizing them into a fiber filament of all-carbon. His invention led to the use of high-performance carbon fibers in 1958 in Cleveland. CF-PEEK was then introduced as a matrix where long and short PEEK fibers were used as the composite matrix to ensure the end product had the qualities of both fibers. Despite the fact that they were inefficient, the fibers contained approximately 20% carbon with low stiffness and strength properties. However, the carbon fiber’s strength potential was realized in 1963 through a new manufacturing process at British research center (David et al., 2014). In the medical field, carbon-fiber-reinforced peek materials range from large scale components such as x-ray application materials to most invisible bolts internally used to support the bones in the body according to Paknikar and Kumbhar (2015). CFR-PEEK materials have for a long time been adopted for use in the medical field in different facets. They are widely used in the orthopedic processes mainly for bone crafts, bone cementing, hip joint replacement, and in the fixation of the bone plates in the body. Hofmann (2016) points out that CFR-PEEK can be fabricated with tensile strength or stiffness in the capability of the bone they replace in the body. As a result, the materials are successfully finding their way into the medical devices as implants to replace the internal body organs and tissues. Historically, many challenges have been faced by implant designers in achieving acceptance from different regulatory agencies globally. However, the uses of carbon-fiber-reinforced peeks are on the rise as a result of technological advancements and innovations. New medical applications and composite materials are gaining popularity and approval in many parts of the US food and drug administration (Garry, 2013). CFR-PEEK are used in the formulation of bone growths for implants such as temporary bone supports and bone screws mainly adopted in the orthopedic repairs. These materials have been adopted for use in the bioresorbable polymers that can safely break down and be absorbed by the body in the rebuilding process of the bone. In the medical industry, the first synthesis requirement is a performance parameter indicating the relative merits of different designs of CFR-PEEK with the primary knowledge that the growth and micro-motion of bones can be used for different purposes in a clinical view. What follows is a finite element code that determines the strains in the bone used as essential parameters in evaluating the performance of the carbon fiber. The CF-PEEK composite is manufactured by the use of a hybrid fabric composing of PEEK and carbon fiber as a matrix that is then modified and treated by low temperature and oxygen plasma. The process is then followed by X-ray photoelectron spectroscopy, Fourier transformation attenuated total reflection infrared spectroscopy (FTIR-ATR), and Scanning Electron Microscopy (SEM) that are essential I relating the functionality and roughness of the carbon fiber surface with the PEEK interfacial adhesion strength.   The plasma treatment is aimed at increasing the roug hness of the carbon fiber surface while the prolonged treatment results into the smoothing. According to Duraccio, Mussano, and Faga (2015), the structural properties of a composite material are determined by the length, volume, and alignment of the carbon fiber it contains. Apart from being strong, carbon fibers have high tensile strength and stiffness but with low weight. It also has a high chemical resistance and is often tolerant to high temperature and excessive heat but with a low thermal expansion as denoted by Garry (2013). According to Cano and Guilemany (2016), the mechanical property of a composite material can be determined by the mechanical properties of CFR-PEEK. Carbon fibers consist of strong and thin crystalline carbon filaments for the strengthening of other materials. David et al. (2014) denote that the fibers can be thinner than the human hair but gets its strength when the fibers are twisted and laid over a coated and molded into plastics or resin. For these mechanical properties, carbon fiber is adapted for use not only in the medical field but many industries such as the military, automotive, and aerospace. There are two main forms of carbon fiber incorporation used in composites for medical applications. Short CFR-PEEKs that consist of short carbon fibers randomly aligned and are mostly less than 0.4 mm, used as producers of the homogeneous material property for the implant. Long CFR-PEEK consists of carbon fibers essentially running the entire width of most composite materials. The long CFR-PEEK has a tensile strength that is greater than 2000 Mpa when compared to the 170 Mpa which is of the short carbon fiber (Aspenberg, 2014). As a result, their controlled alignment of these carbon fibers hence helps in providing a broad range of anisotropic properties that can be controlled for specific functions depending on there the composite material that needs to be made and the use.   Ajioka et al. (2016) denote that carbon-fiber-reinforced peek material is engineered to produce a varying degree of stiffness and strength based on the number and orientation of the carbon fibers used. It is hence easier to help the manufacturer match the elasticity of the bone to be replaced with the composite implant material that will be fixed. On the other hand, Paknikar and Kumbhar (2015) also denotes that using carbon fibers as composite materials is easier since, before their innovations, manufacturers were facing challenges from modulus mismatch of the then used metal implants. For instance, the mismatch was often producing stress shielding; alter loading, and a periprosthetic bone remodeling process that was often detrimental. Commercially available carbon fiber composite materials have been tested in several ways for fatigue cycles but have always proven to be effective and resistant. Nayeri (2014) denotes that the average strength for a 4.5mm implant plate is 19.1 Newton meters while that of a similar 4.5mm stainless steel compression plate is 17.8 Newton meters. The bending strength of available 10-mm CFR-PEEK is averagely 80.3 Nm, while an 11-mm titanium tibial plate bending strength is 43 Nm. This has proven that the testing for wear debris of the implants is significantly lower than the wear debris strength of titanium plates made from the steel as pointed out by Goodman et al. (2011). The same study denotes that the healing and fracture reduction are available for a standard radiograph. The absence of both MRI and computed tomography means that CFR-PEEK for the composite implants has applications for infections, spine, and for oncologic cases. Even though there are several advantages of using the carbon-fiber-reinforced peek composite implants for medical reasons, there are also some specific disadvantages. For instance, they cannot be contoured hence making their use in fracture fixation limited to straight diaphyseal hence calling for a specific locking screw technique anatomically designed for the specific fracture Utech and Boccaccini (2016). At the same time, stiffness can be beneficial to the receiver, but the too much flexibility is as well dangerous as it can lead to pseudarthrosis. The increased fatigue strength of the implants helps in decreasing any possible risk to fatigue failure. However, the radiolucent nature of the carbon-fiber-reinforced peek used in the manufacturing of the implants precludes directly hence visualizes radiography. In his study, Hofmann (2016) denotes that all biomaterial composites intended for use in the body of any living organism have to meet certain conditions, regulatory requirements, and criteria. These include; Carbon-fiber-reinforced peek have found a wide application and use in different facets of the medical sectors. These include bone cementing, bone grafting, hip joint replacements, bone fixating plating, and other forms of bone replacements (Asghari et al. 2017). In the manufacturing and design of prosthetic composite implants used for the replacement of the central bone and the combined joint, the primary objective is often to arrive at an implant with a higher bone growth stimulus but slightly lower that the titanium alloys implants that are currently used (Egger et al. 2017). From the CFR-PEEK innovations, patients can easily get access to rapid and easier proper implant fixation and bone replacement. Achieving these objectives requires the synthesis and structure of the composite implants to consist of three primary elements. In his study, Soboyejo (2017) points out that CFR-PEEK includes bio-glass-ceramic, xenograft, and allografts often used in joint replacements and tissue engineering. They are often made of different layers of long and short carbon fibers; the final product often combines the properties of both the materials used. The resulting product is often mechanically strong but lightweight at the same time. Saleh (2016) also denotes that the materials have low density and can easily resist corrosion. The use of composite body implants has several advantages when compared to the metallic devices that were used before their inventions. It modules if elasticity and fatigue strength makes the CFR-PEEK an ideal composite implant material for bones plates and nails. The disposal of CF-PEEK is becoming a major issue since the different carbon fiber reinforced composite materials are reaching the end of their live services. According to Schinner, and Brandt (2011), over 27 000 tons of CF-PEEK have produced annually. As a result, grinding up the waste material and sending it to landfills or disposing of it through incineration has little appeal to the environment since it is non-biodegradable.   With global warming and climate change policies affecting every global industry, incineration is not the best method of disposal of the material as it will lead to the production of greenhouse gasses as well as smoke, thus leading to pollution. Disposal into landfills also reduces the aesthetic value of the environment turning the areas into wastelands and creating environments for disease-predisposing factors such as stagnant water collection points for mosquito and bilharzia breeding when it rains. As a result, different recycling methods such as pyroly sis have been adopted that strips away the epoxy resin from the fibers while leaving the original properties undamaged. The medical industry is driven and guided by the demands of the medical profession that seeks constant improvements and device innovations for better medical care. Consequently, different composite biomaterials have been tested and studied for use in the medical field and are often commercialized for their advantages of the traditional composite materials that were used before. Carbon fibers have found a wide application and use in different facets of the medical sectors. These include bone cementing, bone grafting, hip joint replacements, bone fixating plating, and other forms of bone replacements. Ajioka, H., Kihara, H., Odaira, C., Kobayashi, T., & Kondo, H.

A short film Script about Zach's phobia's - Movie Review Example Oh no I need to check if the door locks from outside hold on just a sec (Has already dropped the phone and rushes to the direction of the bathroom but he is still talking albeit in a lower voice almost as if he is talking to himself)†¦ I wonder locks automatically last time tried to shut my door bathroom just a bit, it shut itself and scared the heck out of me. (In a whisper walking towards the bathroom), oh dear this door is too heavy, what if I lock myself in? In the other room Emily can be heard trying to make herself heard on the mouthpiece Emily Hey Zack where did you go off to..Zaaack you want me to come or not? Zack (Suddenly remembering that he had been on the phone, he rushes and picks it up). You really must come Emily, he says I have unpacked luggage, a bathroom whose door’s heavier than a bunch of Two ton Trucks Emily (Sarcastically) You know what Zack? I think I will come†¦ Zack (Cutting her off not getting the tone) Oh thank goodness I had no idea how I was going to get through settling in the darkness is setting in and my new bulbs are in my suitcase and I can’t stand the tough of being alone in the dark. I just love the way you handle this stuff, I would be lost without your savage courage and brute strength Emily (Irritated)Hey where did that come from what’s wrong with you? or also have a phobia for courtesy? As I was saying, before your cut me off I will definitely come, I will come tomorrow and see if your million phobias will have killed you or if you can deal with them without acting like a 6 foot baby. (Slams phone) Zack Uh something I said? Oh boy now I have to do this all by myself. (Light bulb moment) hah! I know, necessity as they say, is the mother of all evil, tonight am going to face up to my fears, what’s the worst that can happen anyway? Emily is right, I need to grow up. (He sits down) now, now, now, but that’s a tall order, let me see what do I need to do first? I should make a list of things I am afraid off , that that could take all night. Maybe I should make list of things I am not afraid off, that can’t be very wrong. (Wrings his hands) this is never going to work (He sits down and scribbles on a paper for a minute or so) Luggage, darkness, bathrooms doctors, bridges closets bridges). Zack Am tired of always having to beg for help, (Marches confidently to the bags at the corner, but stops and almost does not touch them when he gets close up he bites his lower lips)Here goes nothing (opens the first suitcase and jumps back nothing happens) Ok not bad I think is could open them all then, all these locked bags give me the creeps who knows what could have snuck in. (As he opens suitcase 2, 3 and four a mouse moves in from the corner and sniffs briefly around the first suitcase, it then climbs in and disappears into the bag. Zack is getting pretty confident and opens all the suitcases). Zack Phew, that’s the worst of the first part, but one phobia is good enough for one day,

Community Health Nursing - Assignment Example The average casualty rate of Ebola is 50% and therefore, samples are not to be extracted from patients. (WHO, 2014) Diagnosis is conducted through various tests; virus extraction by cell structure, serum neutralization test and electron microscopy are examples of diagnostic tests. There is no treatment available for Ebola. However rehydration with intravenous or oral fluids is administered to patients to increase their survival chances. Prevention measures include: fast response to Ebola incidences and isolation of affected victims, proper burial of victims and community engagement towards controlling the disease. There are no proven vaccines for Ebola, though two vaccines are undergoing human testing currently.(WHO, 2014) In case of an outbreak, nurses can educate the affected communities about the disease as ignorance can have dire consequences. Nurses can provide both the facts and myths associated with Ebola and advice them on the best prevention measures. The main ethical issue that Ebola patients face is that they are isolated and kept away from their loved ones for as long as they live. 3. York, G. (Oct. 09, 2014).

Why Huck is Realistic and Tom is Imaginative In The Adventures of Huckleberry Finn by Mark Twain, the connection between Huck and Tom is contrasted several times throughout the novel such as in the beginning of the novel Twain introduced them as friends who were always around each other. Then by the middle of the book Twain shows how Huck lives and thinks for himself out on the frontier and how he uses Jim as a father figure. By the end of the novel Huck and Tom reunite and that’s where Twain gets to touch up and finish up on the contrasting and comparing of Tom and Huck, which will show how Huck grows up and becomes wiser than Tom whom he looked up too.   Ã‚  Ã‚  Ã‚  Ã‚   In the beginning of the book Twain shows how Huck lives and how he was brought up without a real family. Huck is only thirteen and his father even through Pap is a town drunk, but Pap is not a big part of Huck’s life he has still affected how Huck lives because Huck never had a father to look up to. Twain will introduce a father figure to us in the middle of the novel. Tom is an imaginative person. He lives by what he reads in books. Unlike Huck, Tom is raised by a good family and lives a fairly normal life. Tom and Huck are best friends. They first started out by playing bandits and pirates and having little adventures. They always talked about having adventures and killing people. This talk just shows us how Tom thinks Huck just catches on to what Tom says which shows tom as a leader and Huck just does as he says. This idea will remain the same till the end of the book. The only thing that will change is that Huck grows up wiser and older but still doesn’t grow out of doing as Tom says. By the middle of the novel Twain introduces Jim but not just as Jim because he has already done that but he introduces him as Huck’s father figure. Even though jim is a black slave living in the South during slavery, Huck still looks at him as a father figure because Huck never had a living father and what Jim says and how he acts really makes more of an adult than any other character in the novel.

The World is Flat †Thomas Friedman

1. Do you agree or disagree with Friedman’s assessment that the world is flat? Be sure to justify your answer I agree with Friedman that technology has made the world flat. But there is another point of view disagree with Friedman stating that there are still many people that do not have access to technology and for them the world is still round.2. What are the potential impacts of a flat world for a student performing a job search? In a flat world it is far more difficult to get a job because competition will be increasing at an incredible rate. There are currently 1 billion people online in 2006. It is anticipated that 4 billion people will be online by 2010. As the next 3 billion people come online in the next 4 years competition is going to dramatically increase. But the truth is that Students can now perform a global job search right from their apartment. A student in Chicago can accept a job in Tokyo and never leave the apartment, even when the job starts.3. What can stu dents do to prepare themselves for competing in a flat world? Businesses operate using technology and understanding how business and technology relate will help them achieve success. They can use it as advantage in their completion. And they will gain more skills and learn new ideas4. Identify a current flattener not mentioned on Friedman’s list Videophones and collaboration tools allowing people to meet face-to-face even when they are in different parts of the world Technologies such as Voice-over-IP that offer a cheap alternative to traditional long-distance carriers

Lord Of The Flies By William Golding - 1152 Words

Jonathan Vautour Mrs. Fils World Literature 3 November 2015 Simon: Lord of the Flies The book â€Å"Lord of the flies† is story of a group of boys who were marooned on an island and forced to survive and the effect on their moral stability. In the beginning the reader is introduced to the character Simon. He was a skinny vivid little boy whose hair, black as night and coarse, hung down straight over his face (Oldsey and Weintraub 182-183). Golding’s writing style and background can be seen by how he decided to characterize each and every character in the story. Simon was created as a quite boy that played a substantial and crucial role in the story behind this book. Golding shows Simon’s Christ like characteristics through his bravery, kindness, and good morals. Although he appeared as small and weak, Golding gave Simon the heart and bravery of a war hero. Golding however does not make this bravery very obvious in the way he wrote the book. He showed it when Simon was picked to go with Jack and Ralph (Telgen 174-195). The reason Jack and Ralph picked Simon to go with them is a confusing choice at first because Simon was not the most burley character in the book.
