Composites represent a class of materials in which the microstructure has been obtained by material combinations that are unavailable by thermodynamics alone. In these materials, a matrix phase is reinforced by the addition of either particles or fibers. The length scale of the reinforcing phase is normally in the micron range. Composite material properties can be controlled by altering the ratio of matrix to reinforcing phase. For fiber reinforcement, the isotropy of the properties can also be controlled through control of the fiber orientation. 

In this section the mechanical properties of composites will be explored and related to the
properties and volume fraction of the component materials.
