为了研究硅烷偶联剂处理和玄武岩纤维的排列方向对玄武岩纤维/聚丙烯热塑板的拉伸性能的影响,试验采用质量分数为0.75%的KH-550偶联剂对玄武岩纤维进行处理,再将玄武岩纤维和聚丙烯进行混合开松、梳理成网,采用模压成型工艺制备了A（玄武岩纤维经偶联剂处理）和B（玄武岩纤维未经偶联剂处理）两种热塑板,使用Instron3369型万能强力机测试其拉伸性能。结论：KH-550偶联剂改性处理对热塑板的拉伸性能改善明显,与B板相比,A板的横向强度和模量分别提高了91.4%和33.5%,纵向强度和模量分别提高了40.2%和29.5%;A、B两种板材的纵向拉伸性能指标明显优于横向拉伸性能,A板的纵向强度和模量分别是横向的1.7和1.5倍,B板的纵向强度和模量分别为横向的2.3和1.5倍。

In order to study the effects of silane coupling agent treatment and the orientation of basalt fibers on the tensile properties of polypropylene thermoplastic panels reinforced with basalt fibers, the basalt fibers were treated by KH-550 at 0.75 wt%, and then mixed with polypropylene fibers and carded into webs, which were molded into panel A （fibers treated by coupling agent） and B （fibers not treated）. The tensile properties of these panels were determined by Instron 3369 universal tester. Conclusions： The tensile properties of the thermoplastic panels were affected significantly by KH-550. Comparing with panel B, panel A’s tensile strength and modulus in transverse direction improved 91.4% and 33.5% respectively, while those in longitudinal direction improved 40.2% and 29.5%. The tensile properties of both panels in longitudinal direction were better than those in transverse direction： The strength and modulus of panel A in longitudinal direction were 1.7 times and 1.5 times those in transverse direction, while the strength and modulus of panel B in longitudinal direction were 2.3 times and 1.5 times those in transverse direction.
