A composite material is made from two or more constituent materials with significantly different physical or chemical properties. When combined, these components produce a material with a new set of characteristics. The individual components do not completely blend, instead they remain distinct within the finished structure, differentiating composites from mixtures and solid solutions, such as alloys.
Composites are typically composed of a reinforcement, for example manmade fibers such as glass, carbon or aramid, or natural fibers, and a resin matrix that bonds the fibers. They can also include core materials, fillers, additives and surface finishes to provide unique performance attributes. Composites are created with a particular application in mind, and to yield greater strength, efficiency, durability, stiffness, thermal conductivity, abrasion resistance, dimensional stability and aesthetic, among other properties. A versatile medium, they are used across a wide range of industries.
