【Abstract】 TPU and GF (glass fibers) were blended with POM resin to improve the mechanical properties of blending products. Morphology, impact and stretching tenacities were examined with SEM and mechanical testing. Results indicated that both intension and toughness of the blends are improved.If the GF is added less than 25% and the content of TPU is around 30%.更多还原
