摘要
分析测定了不同长度、不同含量、不同处理方法的苎麻纤维增强聚丙烯复合材料的力学性能(包括拉伸、压缩、弯曲、冲击性能),并与纯聚丙烯的性能进行了对比,通过典型的拉伸应力-应变曲线、弯曲应力-应变曲线、压缩应力-应变曲线、伸长率等的分析,并用电镜观察断口形貌,可以找到最佳的配比方案。
The ramie fiber of different length, different content and different dispose methods to reinforce polypropylene were used, and the tensile stress-strain curve, the flexural stress-deflection curve, the compressive stress-deflection curve, the elongation rate and the photos of the rupture interface were analysed, and the mechanical properties(tensile, flexural, compression and impulsion) were studied, and the best manufacture technics of the composites were found.
