摘要

摘要: 将玄武岩纤维置于混杂铺层的压缩侧，研究了碳纤维-玄武岩纤维混杂增强环氧树脂基复合材料的弯曲性能及混杂比对其弯曲性能的影响。通过对试样进行三点弯曲试验得到了材料的弯曲性能，并通过扫描电子显微镜观察材料的失效模式。与纯碳纤维增强环氧树脂基复合材料相比，当混杂比为16.7%和33.3%时，混杂复合材料的弯曲强度明显提升，弯曲强度分别提高12.4%和15.2%，但是其弯曲模量随着混杂比的提升而降低。混杂后的材料及玄武岩纤维增强环氧树脂基复合材料的失效位移都高于碳纤维增强环氧树脂基复合材料，断裂韧性明显提升。从侧面观察可以发现不同铺层在压缩侧、拉伸侧和中间层有不同的失效形式。

Abstract: Flexural properties of hybrid composites reinforced by carbon fiber and basalt fiber were tested and the effects of hybrid ratio on the flexural properties were also analyzed, on the condition that basalt fiber was put on the compressive side. Three-point bending test was performed on the specimen to obtain the flexural properties and failure mode was observed by scanning electron microscopy. Compared with the pure CFRP specimen, flexural strength of the hybrid composites increases obviously, particularly as the hybrid ratio is 16.7% and 33.3%, the flexural strength increases by 12.4% and 15.2% accordingly. Meanwhile, the flexural modulus of hybrid composites decreases along with the increment of hybrid ratio. Fracture ductility enhances significantly and failure displacements of all hybrid composites and BFRP are higher than that of the pure CFRP. Furthermore, various failure modes can be observed on the compressive side, tensile side and middle layer of the hybrid composites.
