Structural materials of metals, ceramics, wood, or plastics with built-in strengthening agents which may be in the form of filaments, foils, powders, or flakes of a different compatible material

Plastics, metals, ceramics, or carbon-fiber materials with built-in strengthening agents These materials are much lighter and stronger than the metals formerly used for such aircraft components as panels, skin, and flight controls
Any engineered material composed of two radically different materials in a tightly bonded matrix and having properties significantly different from either constituent
Solid material that results when two or more substances are combined (physically, not chemically) to create a new material whose properties are superior in a specific application to those of the original substances. The term specifically refers to a structural matrix (such as plastic) within which a fibrous material (such as silicon carbide) is embedded. Fibreglass-reinforced plastic is the best-known composite. Because of their stiffness, lightness, and heat resistance, composites are the materials of choice in numerous structural, reinforcing, and high-performance applications
