Evolution of the design of materials with macrostructure and microstructure. to domestic appliances and the medical supply industry. The reason for this universal utilization of these new materials is their extensive range of physical properties. Their physical properties could comply precisely with the design specification of a product. In the past metallurgists were primarily responsible for the development of new materials. Now these new materials are synthesized by eclectic teams of specialists. The trend of employing eclectic teams of specialists was responsible for the explosive development during the latter half of the twentieth century of a plethora of material classifications too numerous to discuss here. These include the development of a variety of functional materials such as gallium arsenide or magentostrictive materials where the functional properties are exploited in practice instead of the structural properties as in traditional practice. However there is one classification worthy of mention because it is important commercially and is central to chronicling the evolution of a branch of materials science. This class of modern materials is the advanced composites. These engineered materials are synthesized within As an aside it should be noted that the composite materials technologies is not enti sider the recording in Exodus chapter 5 of t Israelites manufacturing bricks from a mixt straw for the pharaoh in Egypt in 450 BC sand years later the French used a combin hair and plaster to create ornate ceilings in Advanced polymeric composite materials the engineering community the opportu cate products with the strongest and stif unit weight.
