Composites are components made up of a combination of two or more distinct materials.

 
A ductile matrix (like resin, for example) binds, shapes, and protects one or more materials with more resistant characteristics, which are called reinforcements (such as fibers, for example).


 The excellent chemical affinity of the matrix with the reinforcements allows the production of the composite with weight, mass, and mechanical properties that are superior and impossible to obtain with conventional materials.
