ABSTRACT
Composite materials are formed by the combination of two or more materials to achieve properties (physical, chemical, etc.) that are superior to those of its constituents. The main components of composite materials, or composites, are bers and matrix. The bers provide most of the stiness and strength. The matrix binds the bers together thus providing load transfer between bers and between the composite and the external loads and supports. Also, it protects the bers from environmental attack. Other substances are used to improve specic properties. For example, llers are used to reduce the cost and improve processability and dimensional stability [34].
