The dependence of the impact toughness of composite materials (layered composites from various types of fabric and various polymer impregnations) on various parameters has been studied. It is shown that the impact toughness of composite materials depends linearly on the number of layers of fabric in the composite structure. The choice of the best configuration of the composite depends on the goal: reducing the thickness or reducing the weight of the composite. An increase in the impact toughness at a concentration of dispersed unoriented CNTs in the composite matrix in the range 2.5-3% was studied
