Review and discussion on Composite Materials Composite material is combination of two or more constituents (materials) that are microscopically combined to produce a more useful material to meet performance and cost of a product. A number of polymeric composite materials have been developed over the years. They can be broadly classified as particle, discontinuous fiber and continuous fiber reinforced composites. Review in the web on polymer composite material products that are successfully developed and used in each of three composite categories. Take at least two (2) products as examples in each case, state the constituents, performance (density, strength, stiffness and durability) and the cost; and discuss why they are successful and why not? Discuss and provide your own opinion. If needed you can compare the performance with aluminum/steel.
