摘要/Abstract

摘要： 本文研究了不同铺层顺序对亚麻/玄武岩纤维混杂增强复合材料力学性能的影响。通过树脂导流成型工艺制备了纯亚麻纤维、纯玄武岩纤维,及两种铺层的亚麻/玄武岩纤维混杂增强复合材料层合板,分别进行低速冲击及冲击后弯曲测试,分析铺层顺序对混杂复合材料力学性能影响及失效机理。研究发现,在低速冲击测试中,混杂复合材料的力学性能介于纯亚麻纤维和纯玄武岩纤维复合材料力学性能之间。[B₄F₄]_S(其中B表示玄武岩纤维层,F表示亚麻纤维层)表现出比[F₄B₄]_S更高的峰值力,且[B₄F₄]_S吸收的能量更高。在三点弯曲测试中,未损伤混杂复合材料的力学性能介于纯亚麻纤维和纯玄武岩纤维复合材料力学性能之间。冲击损伤后,与纯亚麻纤维和纯玄武岩纤维复合材料相比,两种铺层的混杂复合材料的冲击后弯曲强度保持率均更高,且在相同冲击能量下,[F₄B₄]_S的冲击后弯曲强度保持率更高。

Abstract: This study examines the effects of different layering sequences on the mechanical properties of flax/basalt fiber hybrid reinforced composites. The resin transfer molding process was used to prepare pure flax fiber, pure basalt fiber, and flax/basalt fiber hybrid reinforced composite laminates with two different stacking sequences. Low-velocity impact and post-impact bending tests were performed to reveal the influence of layering sequences on the mechanical properties and failure mechanisms of the hybrid composites. The study found that in the low-velocity impact test, the mechanical properties of the hybrid composites were between pure flax fiber and pure basalt fiber composites. [B₄F₄]_S exhibited a higher peak force than [F₄B₄]_S(where B denotes the basalt fiber layer, F denotes the flax fiber layer), and the energy absorbed by [B₄F₄]_S was higher. In the three-point bending test, the mechanical properties of the undamaged hybrid composites were between pure flax fiber and pure basalt fiber composites. However, after impact damage, the post-impact bending strength retention rates of both hybrid composites were higher than those of pure flax fiber and pure basalt fiber composites, and under the same impact energy, the post-impact bending strength retention rate of [F₄B₄]_S was higher.

Key words: flax fiber, basalt fiber, fiber hybrid reinforced composites, impact performance, bending strength
