摘要

本研究对玻璃纤维和玄武岩纤维增强聚丙烯复合材料在准静态和动态条件下的行为进行了研究。复合材料采用真空辅助压缩成型法制造。研究了复合材料在准静态拉伸和压缩条件下的失效情况,以及在动态条件下低速冲击和超音速冲击加载下的失效情况。研究结果表明,玄武岩纤维增强聚丙烯(Basalt/PP)复合材料的拉伸和压缩强度高于玻璃纤维增强聚丙烯(Glass/PP)。在低速冲击(LVI)下,玄武岩/聚丙烯没有穿透,50 J 的变形可以忽略不计,但玻璃/聚丙烯在 50 J 的冲击下穿孔,背面出现各种破坏形态。由于聚丙烯具有延展性,纤维与基体的界面粘附在超音速冲击载荷中起着吸收冲击波能量的重要作用,这两种复合材料通过基体和纤维的破坏吸收能量,在冲击载荷下,层压板没有发生脆性破坏。

Performance analysis of fiber-reinforced polypropylene composite laminates under quasi-static and super-sonic shock loading conditions for impact application
In the present research, glass and basalt fiber-reinforced polypropylene composites’ behaviour in quasi-static and dynamic conditions is studied. Composites were fabricated by vacuum assisted Compression molding method. Composites failure under quasi-static tension and compressive conditions was studied along with its failure behaviour under low-velocity impact and super-sonic shock loading under dynamic conditions. The study results showed that basalt fiber-reinforced polypropylene (Basalt/PP) composite’s tensile and compressive strength is higher than glass fiber-reinforced polypropylene (Glass/PP). The Basalt/PP showed no penetration against low velocity impact (LVI) with negligible deformations till 50 J. However, the Glass/PP perforated at 50 J with various failure patterns occurring at back side. The fiber-matrix interface adhesion plays an important role in super-sonic shock loading by absorbing shock wave energy due to ductile nature of polypropylene and the two composites absorbed energy via matrix and fibers failure, no brittle failure of laminates occurred under shock loading.
