Bending strength test were carried out on injection-molded and transfer-molded short glass fiber reinforced phenolic resin composite. The effects of the short fiber content (V_f=0%, 20%, 50%), distribution of fiber orientation on bending strength and elastic modulus were investigated in comparison with molding processes. The bending strength and elastic modulus became higher with increasing fiber content. Increasing rate of bending strength and elastic modulus on injection-molded were higher than transfer-molded. Mechanical properties evaluation diagram was prepared to predict the bending strength and elastic modulus with modifyed rule of mixtures proposed by Fukuda and Kawata, and Fukuda and Chou. By comparing the predicted elastic modulus and bending strength with experimental results, the validity of the diagram is examined with an maximum uncertainty of 15%.
