Mechanical Engineering

Composite is consist of two phase, one is Reinforcing phase and other is Matrix. Reinforcing phase is like fibers, particles, flakes. Matrix  is a continuous phase. Example of composite: Concrete reinforced with steel, epoxy reinforced with fibers. Naturally found : Bone-salt plates made of calcium and phosphate ions reinforcement soft collagen. Some advanced composites are: graphite/epoxy, Kevlar/epoxy, fiber glass etc.

A Composite Material is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. Composite Material was introduced long time ago. But was in different form. Bricks were made by using clay and straw. It was ancient use  of composite material. But now-a-days composite materials example: carbon, glass, epoxy etc.
