| 摘 要： | 考察了三维编织碳纤维/芳纶纤维混杂增强铸型尼龙(简称HF/MCPA)复合材料的力学性能,着重分析了复合材料的冲击、剪切和弯曲性能。试验结果表明:碳纤维和芳纶纤维混杂复合材料不仅有较好的弯曲强度、剪切强度,同时冲击强度也很好。随着碳纤维体积分数的增加,混杂复合材料的冲击强度降低;横向剪切强度先增大后降低;纵向剪切强度逐渐增大,出现最大值;弯曲强度和模量随之提高,达到最大值后开始下降,最大值时CF∶KF为3∶2。

| Abstract: | In this paper, the mechanical properties of 3D-braided carbon and Kevlar fibres hybrid reinforced monomer cast nylon (HF/MCPA) are studied. The impact, shear and flexural properties of HF/MCPA are tested. The results show that HF/MCPA has excellent impact, shear and flexural properties. With increasing of carbon fibre volume fraction, the impact property of HF/MCPA decreases, the transverse shear property rises and then fall, the lengthwise then property increases and reaches the top at the ratio of CF:KF=3∶2, and the bending strength and modulus rises and then fall after reaching the top. |
