| Abstract: | Bamboo particles reinforced polypropylene(PP) composites were prepared by extrusion method.The mechanical properties change and dimensional stability of bamboo particles reinforced PP composites after ultraviolet accelerated aging,and damp-hot aging were studied.The results showed that the bending strength and bending modulus had no significant change after 200 hours ultraviolet accelerated aging,and the width and thickness of the samples did not change significantly also.Damp-hot aging had a significant effect on the bending strength and bending modulus.After soaking in boiling water for 2 h,the retention rates of the bending strength and bending modulus were of 81.5% and 82.4%,respectively. |
