摘要:
采用无纬带缠绕层压成型工艺制备硼纤维/环氧单向复合材料，通过对硼纤维/环氧单向复合材料的宏观和微观拉伸断口形貌观察，分析了硼纤维/环氧单向复合材料的破坏模式。结果表明：当树脂基体的断裂延伸率较小时，硼纤维/环氧单向复合材料的破坏模式主要是非累积型破坏。随着树脂基体的断裂延伸率增大，硼纤维/环氧单向复合材料的破坏模式向损伤累积型破坏转变。

Abstract:
Unidirectional boron fiber/epoxy (Bf /epoxy) resin composites were fabricated with winding and compression molding, and the failure modes of the unidirectional Bf /epoxy resin composites under tensile loads were studied by observing macro- and micro- fracture surfaces of the Bf /epoxy resin composites. The results show that the failure modes of the unidirectional Bf /epoxy resin composites are mainly the non-accumulating failure when the elongation to fracture of epoxy resin is small. While the failure modes of the unidirectional Bf /epoxy resin composites are gradually changed into the accumulating failure with increasing the elongation to fracture of epoxy resin.
Key words:  failure modes  boron fiber  epoxy resin  unidirectional composites
