The RF/PTW/PP composites were prepared by torque rheometer blending and transfer molding. Also, the orthogonal experiment design was used, and a series of analyses have been done on the strength and toughness of the material. On the basis of the analysis, RF/PTW（ 10% ）/PP composites were prepared again, their mechanical properties were tested, and their fracture surfaces were analysed by the SEM. Results show that the effect of the whisker content for the tensile and impact strength is greater than that of the fiber content, and the fiber con...
