The paper presents the results of experimental investigation and numerical modeling of deformation and fracture processes of beams made of composite material under dynamic three-point bending. The specimens are made of composite material with polymer matrix reinforced with layers of carbon fiber fabric. Loading of the specimens was carried out in the direction perpendicular to the reinforcement plane and in the reinforcement plane. Loading of specimens and calculation of quantitative characteristics of the deformation process were carried out using measuring bars. Time dependences of the forces acting on the specimens from the side of the loading and output measuring bars as well as deflection and deflection rates were experimentally plotted. High-speed video registration was used for visual analysis of specimen fracture processes. Numerical modeling of experiments was performed in the LOGOS software product. A material model with progressive fracture and strain rate hardening was used to describe the behavior of the composite material.
