Popis: A low-velocity vertical impact method was considered on various composite specimens. Impact damage areas were studied by the ultrasonic echo-pulse method, the damage size dependence on impact energy was determined in various polymer composite materials. Damaged specimens were tested in compression to determine their residual strength. Layer-by-layer assessment of damage was carried out for a set of specimens by the computed tomography.
