Overall or effective material parameters of composites usually are obtained by experimental methods applied to composite specimens. If such overall properties are not available, however, but constituents’ parameters can be obtained, analytical or numerical micromechanical techniques must be used. The same methods can also be applied to the design of composites or to characterize the composite by recalculating individual parameters from the measured overall behavior. Therefore, in this Chapter some simple and some more advanced methods for determining the overall, i.e. effective or smeared out, material properties of fiber reinforced composites from the material data of their constituents and their micro-geometrical arrangement are presented.

It should be mentioned that some idealizations must be made in this engineering approach. For example, material parameters of the constituents measured separately for matrix (as a bulk material) and fibers normally differ from the in-situ properties.
