Abrasive wear in three-phase waste-based polymeric particle composites

Abstract

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 two-and 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 3 by two body abrasion and 0,008 cm 3 by three body abrasion).Keywords: three-body abrasion; three-phase polymeric particle composite; two-body abrasion; waste Abrazivno trošenje kod kompozita sastavljenih od čestica polimera s tri faze baziranih na otpaduIzvorni znanstveni članak Eksperiment se zasniva na abraziji s dva i tri tijela u sustavima trofaznih kompozita od otpadnog materijala. Otpornost kompozitnih sustava na abraziju definira se ne samo fizikalno-mehaničkim odnosima pojedinih faza kompozita nego i uzajamnom interakcijom faza te međupovršinom matrica-punilo. Kako bismo opisali otpornost kompozitnog sustava na abraziju primijenili smo abrazivno trošenje "s dva tijela" na abrazivnom platnu i abrazivno trošenje "s tri tijela" na stroju s gumenim diskom uz abraziju pijeskom. Rezultati pokazuju da se ne može pronaći jasna korelacija između abrazija s dva i tri tijela sve dok se radi o smanjenju volumena sustava. U isto vrijeme, nije potvrđen jasan odnos između tvrdoće mjerene prema Brinellu i smanjenja volumena i pojedinačnih vrsta trošenja. Kompozit koji se pokazao najotpornijim na abrazivno trošenje bio je onaj s 30 % punila koji se u odnosu 6:1 sastojao od metalnih strugotina i F80 frakcije otpada korunduma u dvo-komponentnoj epoksi smoli (smanjenje volumena bilo je 0,0395 cm 3 kod abrazije s dva tijela i 0,008 cm 3 kod abrazije s tri tijela).

Investigation of Mechanical Properties of Horn Powder-Filled Epoxy Composites

“…Krishnaiah [21]. Valasek and Muller have described "two-body" abrasive wear on an abrasive cloth and a "three-body" abrasive wear on a machine with a rubber disc using sand abrasion and showed that there is no clear correlation between the two and three-body abrasions as far as the volume decrease is concerned [22]. Valasek and Muller have studied the abrasive wear resistance and hardness of waste corundum particle/epoxy composites with waste Al 2 O 3 as filler and found that wear resistance and hardness have increased due to the inclusion of corundum [23].…”

Influence of Plasma Treatment on Mechanical Properties of Cellulose-based Fibres and Their Interfacial Interaction in Composite Systems

“…Natural fibres (generally natural fillers) are renewable resources that can often substitute for fossil fuels, which dominate the material engineering industry (Ruggiero et al 2015;Valášek and Müller 2015;Müller et al 2016;Ruggiero et al 2016). Growing these fibres is nature-friendly in most cases.…”
