The paper deals with the testing of composite materials based on corundum, silicon carbide and glass. The object of the experiments was a particle polymeric composite, whose continuous phase was in the form of a two-component epoxy resin and a discontinuous phase (reinforcing particles) of corundum, silicon carbide and glass of a specific particle size from 4.5 to 260 µm. The research was focused on the evaluation of abrasive wear resistance and hardness of the tested materials. A considerable improvement of the values obtained at measuring the abrasive wear resistance was reached at hybrid composite materials filled with three different components, when 98% improvement was reached compared to the epoxy resin without the filler. The hardness increased up to 35% by adding the filler. The particle size influenced properties of the polymeric composite as the particles of larger sizes bring a positive influence on the wear resistance and the hardness HBW 10/250/30.Keywords:
