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%.
