Abstract
Abstract
The article summarizes the experimental results from the experiments of loading thin composite plates by low-speed impact. The plates are made on a 3D printer from the material onyx-glass fiber and onyx-carbon fiber. Another investigated material was a pre-impregnated (resin-kevlar) plate. The theory of the impact load of the plate and basic parameters of the tested plates are presented. The plates were repeatedly loaded with low-speed impact weights, the responses of the plate to the impact (wave propagation in the plate) were measured. The experiment is supplemented by a numerical analysis. Damage to the plates was evaluated by NTD methods.
