| 摘 要： | 制备了碳纳米管(CNTs)/碳纤维(CF)/环氧树脂(EP)三元复合材料。研究了CNTs含量对复合材料层间剪切强度、弯曲强度和弯曲模量的影响,并采用场发射扫描电镜分析了CNTs在基体树脂中的分散情况。结果表明:复合材料性能的变化源自于CNTs在基体树脂中的分散状态。当CNTs含量为0.2%(wt,下同)时,复合材料剪切强度和弯曲强度达到最大值,分别为99.2MPa和1811.4MPa,但其弯曲模量下降了8.7GPa。当CNTs添加量达到1%时,其弯曲模量达到135.9GPa,较未加入CNTs时提高了11.1%,层间剪切强度和弯曲强度分别降低了5.5MPa和359.5MPa。

| Abstract: | Epoxy resin(EP) /carbon fiber(CF) composite was modified by carbon nanotubes(CNTs),and the effects of CNTs content on the interlaminar shear strength(ILSS),flexural strength and flexural modulus of EP/CF composite were studied.The results showed that the mechanical properties of composite could be obviously improved by adding CNTs.When CNTs content was 0.2wt%,the interlaminar shear strength and flexural strength reached the maximum 99.2MPa and 1811.4MPa,while the flexural modulus decreased by 8.7GPa.When CNTs content was 1wt%,the flexural modulus reached the maximum 135.9GPa,which was 11.1% larger than this of composite without CNTs,meanwhile the the interlaminar shear strength and flexural strength decreased by 5.5MPa and 359.5MPa,respectively. |
