This paper describes a material model for evaluation of the thermoelastic properties of fiber composite materials having a spatial distribution of fiber orientations. The approach is to construct a material model having a finite number of fiber orientations in a repeating unit cell. The basic material model is a minimechanical model based on the concept that a material system can be regarded as an assemblage of unit cells.

The unit cell models are constructed from impregnated yarn bundles and interstitial matrix regions. The predicted properties of these unit cells are those required for use in thermostructural analysis computer codes. The model treats anisotropic constituents, dispersed voids, temperature-dependent constituent properties, and fiber bundles oriented in many different directions.
