'''Composites''' are a class of materials manufactured from more than one type of raw product. A typical example would be that of [[synthetic fibres]] set within a [[resin]] as in the case of glass-reinforced plastic (GRP, or "fibreglass") or an [[aramid]]-based material (such as [[Du Pont]]'s [[Kevlar]]).
Composites are increasingly widely used in the automotive, marine and aerospace industries. In the latter case they were vital in developing [[stealth]]y aircraft, where composites replace metals to reduce radar reflections. Composites came about due to great advances in [[plastics]] and [[recycling]]. They allow engineers the option of replacing heavy metal components with lightweight composite ones of the same strength. They have also replaced many non-metallic materials such as wood, where they offer much greater strength for the same low weight.
