摘要 采用微球脱粘实验法研究了炭纤维/尼龙6微复合材料的界面微观力学性能,考察了不同的拉伸速率对界面微观力学行为的影响。结果显示:在拉伸速率为3.5,4,4.5mm/min,纤维在树脂基体中的包埋长度le<140μm时,树脂微球从纤维上脱粘时的力值Fmax与包埋长度le保持着良好的线性关系;当拉伸速率为5mm/min,包埋长度le>70μm时,纤维就断裂了,试样失效。 Micromechanical performance of carbon fibre reinforced PA6 resin micro-composite was studied by the microbond test which has been well accepted as the most important micromechanical test for evaluating the interfacial properties between the fibre and matrix.The effect of different stretching rate on the interfacial properties was investigated.The results showed that the maximum force(Fmax)demonstrated good linear relationship with embedded length(le)with the stretching rate 3.5,4,4.5mm/min when le was less than 140μm,and the carbon fibre was broken without matrix debonding when the stretching rate was 5mm/min in the case of le bigger than 70μm.
