- Abstract
- This article evaluates the effect of single-walled carbon nanotubes (SWCNT) on the strength and crack resistance of CFRP. Comparative results of static and fatigue strength of the SWCNT modified PCM material with soft lay-up are presented. The static tensile strength is determined by GOST R 56785-2015. The fatigue strength of elementary samples was determined using GOST 57143-2016 at 60 and 80 % of the maximum static load. A quantitative assessment of the crack density in the layers in the directions has also been determined 0/+45/-45/90 after pre-cyclic loading "tension-tension".
