玄武岩纤维布增强环氧树脂复合材料研究

以玄武岩纤维平纹布 (BF) 加入到环氧树脂 (EP) 中，采用模压工艺制备BF／EP 复合材料，研究加入不同层数的玄武岩纤维布对复合材料力学性能和断裂韧性的影响。实验结果表明，BF/EP复合材料的弯曲强度、冲击强度和断裂韧性明显优于环氧树脂；与未加BF的环氧树脂相比，加入三层BF后复合材料的弯曲强度提高了2.76倍，缺口冲击强度提高了19.67倍，无缺口冲击强度提高了5.94倍，KIC提高了2.97倍。

Study on Epoxy Resin Composites Reinforced by Basalt Fiber Cloth

The BF/EP composites were prepared by embossing with basalt fiber plain cloth (BF) added to epoxy resin (EP). The effects of different layers of basalt fiber cloth on the mechanical properties and fracture toughness of the composites were investigated. The experimental results show that the bending strength, impact strength and fracture toughness of BF/EP composites were significantly better than that of epoxy resin. Compared with the epoxy resin without BF, the bending strength of the composite increased by 2.76 times after adding three layers of BF. The notched impact strength increased by 19.67 times, the unnotched impact strength increased by 5.94 times, and the KIC increased by 2.97 times.
