peculiarities of CC material as well as their influences upon the material behavior are discussed. Many assumptions must be made regarding some of the material parameters; an intelligent approach to making those assumptions is presented.
Material models for evaluating thermoelastic properties of fiber composite materials having a spatial distribution of fiber orientations are discussed. The approach is to construct a material model with a finite number of fiber orientations in a repeating unit cell. This basic material model is a mini-mechanical model based upon the concept that a material system can be regarded as an assemblage of unit cells.
