Principal elastic moduli of unidirectional composites with aniso tropic filaments are predicted from available elasticity solutions of multiple-inclusion problems. Measured data obtained from composites made of graphite filaments and epoxy resins agree well with the predicted values. Filament anisotropy is shown to have significant effects on the composite elastic properties.
