About Composite

A composite, by definition, is made from several different substances.  By combining different merits of substances, composites usually bear very good mechanical properties.  Composites are usually seen as fiber composites, metal composites, and ceramic composites.
Fiber Composites
Fiber composites are made from fibers and resins.  They are anisotropic, which means different properties in different directions.  They usually have very high strength and other good mechanical properties with very light weight.  Fiberglass, carbon fiber Aramid are three often seen fibers.
