Composites materials are the ones that result from the combination of one or more reinforcement materials and a binding or matrix, without producing a chemical reaction between them.
In advanced composites, this reinforcement is usually in fiber form such as carbon, glass or Kevlar/aramid fibers, and essentially add strength and stiffness. The matrix are resins like epoxy or others, that essentially add structure to the composite material, filling the gaps between the reinforcement materials, keeping them in their relative positions and providing compressive strength, resulting in a final laminate or product with exceptional structural properties not present in the original materials.
