玄武岩/玻纤/丙纶复合材料的研制及其结构和性能

Manufacture of BF/GF/PP Composites and the Structure and Performance

以玄武岩纤维、玻璃纤维为增强纤维,丙纶为基体纤维,通过线形设计、预制件结构设计、直接热压成型工艺研制出一种玄武岩/玻纤/丙纶结构复合材料。观察并分析其结构可知:成型过程中,基体丙纶熔融后浸入组织内部包覆增强纤维,增强纤维则保证织物组织在复合材料中完整无缺,尤其纬纱满足复合材料在厚度上的要求。对制得的复合材料进行拉伸性能测试,结果显示:三维正交组织结构与三维角联锁组织结构复合材料相比,前者的弹性模量和抗拉强度均小于后者,拉伸应变大于后者。

This paper develops a fiber hybrid reinforced composite with basalt fiber and glass fiber as reinforced fiber and polypropylene as base fiber. The process includes design of yarn form, prefabricated member structure and molding process, etc. Basing on the observation and analysis of composite＇s struc- ture, it can be obtained that the melt polypropylene immerses in the fabric and the reinforced fibers ensure the fabric structure in the composite intact. Especially the weft yarn meets the thickness requirement of composites. This paper also tests the tensile properties of the 3D angle interlock and orthogonal compos- ites. Results show that the former has better modulus of elasticity and tensile strength, and the latter has better tensile strain.
