This paper presents a method for evaluating the effect of loading parameters on the strength of ani-sotropic unidirectional carbon-fiber composite material under tension in the plane of orientation of the fibers. Experimentally studied mechanisms of deformation and fracture of the samples shows the dependence of the mechanical properties of reinforced carbon fiber reinforced plastics. The objective of the study is to determine the applicability of CFRP for strengthening by external reinforcement has lost the strength of the stretched zones of concrete elements, as well as analysis of the degree of influence of parameters of loading of the structures on their strength after amplification.
composite materials, fiber-reinforced plastic, carbon fibre external reinforcement.
