Abrasive Wear in Three-phase Waste-based Polymeric Particle Composites

Original scientific paper The experiment centres on two and three body abrasion in three-phase waste-based composite systems. The composite systems abrasion resistance is defined not only by the physical-mechanical relationships of the separate phases of the composite, but also by the mutual interaction of the phases and on the matrix-filler interface. To describe the composite system abrasion resistance, we used a "two-body" abrasive wear on an abrasive cloth and a "threebody" abrasive wear on a machine with a rubber disc using sand abrasion. The results show that we cannot find a clear correlation between the twoand three-body abrasions as far as the systems’ volume decrease is concerned. At the same time, no clear relationship was confirmed between the hardness measured according to Brinell and the volume decreases with individual kinds of wear. The composite that proved the most resistant to abrasive wear was the one with 30 % filler based 6:1 on metallic chips and the F80 fraction waste corundum in two-component epoxy (the volume decrease was 0,0395 cm by two body abrasion and 0,008 cm by three body abrasion).
