Composites are engineered materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure. The combined performance of the constituent materials is superior to their individual performance, resulting in a new multi-component system with completely new and improved properties.
Fiber composites comprise a combination of technical fibers embedded in a synthetic matrix (normally of epoxy resin). The matrix holds the fibers together and protects the composite from environmental influences. The fibers impart the composite material with the necessary strength and stiffness. The main and most frequently used fiber composites today are carbon fiber reinforced plastics (CFRP) and glass fiber reinforced plastics (GFRP).
