A model is developed to predict thermal expansion coefficients and elastic moduli of multicomponent (hybrid) composites. The model includes the influences of fiber aspect ratio; isotropic and anisotropic fiber materials; planar, three-dimensional or arbitrary fiber orientation; hollow and solid spherical reinforcements; and voids. The first step in the procedure is to predict the properties of an aligned-fiber single-reinforcement composite for each reinforcement type. Various micromechanics approaches are used, depending on the type of reinforcement. Predictions of the model agree well with experimental elastic and thermal properties of short-fiber/hollow-sphere composites designed for VHSIC board applications. 25 refs.
