Abstract: Structure and mechanical properties of CFRP modified by SWCNT with different content (0.1, 0.2 and 0.3 wt. %) have been studied in the present paper. The structural investigations include SEM imaging while the mechanical properties have been characterized via tensile and flexural tests. The main functional feature of such hybrid composite is an electrical conductivity, which has been also measured. Out-of-plane conductivity has been enhanced up to ~66 S/m from dielectric unmodified CFRP. It has been shown that tensile properties stay almost unchanged, while flexural strength and modulus have increased by 22% and 16% correspondingly.
