| 摘 要： | 采用机械共混及模压成型工艺制备了剑麻纤维(SF)/聚丙烯(PP)复合材料,研究了SF表面处理方法及其含量对复合材料晶态结构、力学性能、流动性能、吸水性能和微观结构的影响。结果表明:表面处理能有效增强SF和PP基体的界面黏合性,使复合材料的力学性能和流动性能提高,吸水率下降,其中,超分散剂的改性效果更加显著;但SF的表面处理并未改变基体树脂PP的晶态结构,复合材料中的PP仍以α-晶型为主。

| Abstract: | SF/PP composite was prepared by mechanical blending and compression moulding.The effects of surface treatment agents on crystal structure,mechanical property,flow ability,water absorption and microstructure of the composite were studied.The results show that:surface treatment of SF can effectively enhance the adhesiveness,improve the mechanical property and flow ability,and decrease water absorption of the composites,wherein the modification effect of super-dispersant is more obvious;but the crystal structu... |
