Composite materials is also called composition materials...

Composite materials is also called composition materials or shortened to composites. They may be selected to give unusual combinations of weight, stiffness, high temperature performance, strength, corrosion resistance, conductivity, or hardness. They are materials made from two or more constituent materials with significantly different physical or chemical properties. When combined, they produce a material with different characteristics from the individual components. The individual components will remain distinct and separate with the final structure. Composite materials are made up of some individual materials called constituent materials. There are two categories of these constituent materials. The first is matrix and second is†¦show more content†¦However, carbons react with aluminium to generate a brittle and water soluble compound (Al4C3) on the surface of the fibres. The carbon fibres are coated with nickel or titanium boride to prevent this reaction. Polymer matrix Composite is a composite material made from a polymer resin. They are not as strong or heat resistant as metal matrix and ceramic matrix composites. These materials use a polymer based resin as the matrix composite, and a variety of fibres such as carbon, glass as the reinforcement. Polymer matrix materials are also called a resin solution. There are many producer used it to produces composite. Besides that, there are many different polymers available such as polyester, vinyl ester, phenol, epoxy, Polyether Ether Ketene (PEEK), and others. Polymer Composite Material contains two broad types, which is thermosets and thermoplastics. Thermosets- Thermosets are usually formed from low-viscosity liquids that become cross-linked by combination with a catalyst or by the application of some external form of energy, such as heat or radiation such as UV light and other types. The earliest composites were made with a phenolic thermosetting matrix. Then the epoxides followed, then the ureas, the unsaturated polyesters, and the silicons, and now there are considerably more. From the usage standpoint, the most important materials are the first three which is phenolic, the epoxies and the unsaturatedShow MoreRelatedKevlar3486 Words   |  14 Pagesscience of the very curious material: Kevlar ®. Our aim is to create a very informative piece of writing that can be of reference to our project subject, when in need. Upon taking up this project we conducted some very superficial research initially. Our research led us to believe that Kevlar ® is a rather well known material that has been used in bullet proof vests for the last couple of decades. In addition to this, we came to the conclusion that Kevlar ® is also a material that has the potentialRead MoreThe Energy Supply And Usage Of Renewable Energy10339 Words   |  42 Pagesimproved to help PRO become cost-effective.
