连续式蒸汽爆破对PP/棉杆纤维复合材料力学性能的影响

摘要

In this paper, with continuous steam exploded cotton stalk as reinforcing fiber, polypropylene (PP)/cotton stalk composites were prepared by compress molding.The effects of steam explosion conditions such as moisture contents and steam explosion times on the mechanical prosperities of the composites were investigated.The results showed that this pretreatment improved the mechanical properties of the composites.Especially, when the water content was 40％ and the explosion was twice, the composites performed the best.%以连续式蒸汽爆破预处理的棉杆作为增强纤维,通过模压成型制得聚丙烯(PP)/棉杆纤维复合材料.研究了蒸汽爆破条件中纤维含水量及爆破次数对复合材料力学性能的影响.结果表明,该预处理使复合材料力学性得以改善.当纤维含水量为40%、爆破次数两次时,获得的复合材料综合力学性能最佳.
