Abstract

Hybrid composite materials reinforced with nanoscale additives provide better mechanical properties than traditional composites. Carbon-fiber-reinforced polyether ether ketone with various layups modified by 0.05-0.36 wt% of single-wall carbon nanotubes was experimentally studied. The influence of the nanotubes on the mechanical properties of the composites, found in tensile and bending tests, and on their electrical conductivity was studied and discussed. Adding 0.15 wt% of SWCNTs between layers of prepregs led to an increase in the tensile strength by 9.9% and flexural strength by 5.5%. The electrical conductivity of the unidirectional composite has not been changed significantly after the incorporation of SWCNTs, while for orthotropic layup it increases by 65%.

喷涂技术沉积的 SWCNT 对 Peek 层压板机械性能和导电性的影响

与传统复合材料相比，使用纳米添加剂增强的混合复合材料具有更好的机械性能。实验研究了由 0.05-0.36 wt% 的单壁碳纳米管改性的不同铺层的碳纤维增强聚醚醚酮。研究讨论了纳米管对拉伸和弯曲试验中发现的复合材料机械性能及其导电性能的影响。在预浸料层之间添加 0.15 wt% 的 SWCNT 可使拉伸强度提高 9.9%，弯曲强度提高 5.5%。加入 SWCNT 后，单向复合材料的导电性没有明显变化，而正交铺层的导电性则提高了 65%。
