Müller Miroslav author Kejval Jiří author text journal article 2017 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. hardness; mechanical properties; polymeric composite; strength; testing wear 10.17221/79/2015-RAE https://rae.agriculturejournals.cz/artkey/rae-201703-0002.php https://rae.agriculturejournals.cz/artkey/rae-201703-0002.php continuing 63 3 106 114 2017 12129151 periodical academic journal
