A mathematical material model has been developed for the computation of thermoelastic properties of composites formed from spatial arrays of oriented fibers in a matrix. It can be used for determination of elastic moduli and thermal expansion coefficients of composites such as carbon/carbon composites, containing a large number of discrete fiber directions. The model is applicable to the case of anisotropic constituents having temperature-dependent properties and includes the effects of dispersed voids in the matrix. Calculations made with the model show that there are significant differences between the general nature of the properties of multidirectional composites having different numbers of fiber directions.
