Composites are combinations of materials, like fiberglass, in which two or more structurally complimentary substances such as metals, ceramics, glasses and polymers are combined to produce structural or functional properties which are not possible with the
individual components. An application is the production of low-cost aluminum metal matrix composites for high-performance structural components. Silicon carbide whiskers (small
crystalline materials) have been used to reinforce the aluminum matrix, resulting in a structure that is lighter in weight and equal to or greater in strength than conventional materials. The reinforced composites have applications in aerospace projects, and potential military applications such as track vehicle tread shoes (See Figure C-6), power train parts, and missile structures.
