“…With anorganic waste filler it is possible to agree with the statement arising from the work of Sataphy et al [7], who found out that this inclusion will increase resistance towards two-body abrasion. Resistance of two and three-body abrasion varies from one waste-based composite system to another and so it is not possible to agree with the conclusion of Kumar et al [18] and Suresha [19], who state that if the composite system is resistant during two-body abrasion, this characteristic would be prominent also by three-body abrasion.…”

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).

“…Th e abrasive wear resistance was based on the standard ČSN 01 5084 (1973). Th is method was implemented on polymeric materials, analogically as in the following works (Brožek, Nováková 2008;Suresha, Ravi Kumar 2010;Valášek, Müller 2011), where the abrasive cloth on the basis of SiC and of grits 320 and 600 were used for tests.…”

Valášek P., Brožek M., 2013. Degradation of polymer particle systems in agrocomplex. Res. Agr. Eng., 59: 46-50.One of the possibilities of recycling waste from blasting processes is the application of these secondary materials in polymeric matrix, where the primary material is replaced with the secondary one. By this quite specifi c recycling process a new material arises -polymeric particle composite. It is a case of two phase system, properties of which are defi ned by the mutual interaction of single components. One of the possible applications of these systems is agrocomplex. Systems used in agrocomplex environment can be subjected to specifi c infl uences, which change their mechanical properties in some time -degradation occurs. Th is contribution occupies with degradation processes of polymeric particle composites on the basis of waste-corundum after exposure to chosen degradation media, which are typical for agrocomplex environment. Changes of hardness, abrasive wear resistance and tensile strength in dependence on exposure time were tested.

“…Furthermore, the purpose of adding fillers into the polymer matrix is to increase the mechanical behavior, but their effect on the wear behavior is not beneficial. The adding of non-thermoplastics fillers into the blend had the detrimental effect on the abrasive wear behavior of the polymer [21]. The effect of fillers on the mechanical behavior is most appreciable, but there was a reduction in elongation of polymer composites.…”

A B S T R A C TThree body abrasive wear behaviour of Polyamide 66 and Polypropylene (PA66/PP) blends in different weight percentages of 95/5, 90/10, 85/15, 80/20, 75/25 and 70/30 are investigated. The experiments were carried out as per ASTM G65 by using rubber wheel abrasion tester (RWAT). The tests were conducted for a load of 50 and 75 N at a sliding velocity of 2.5 m/s with an abrading distance of 500, 1000 and 1500 m using fine abrasive dry sand particles as third body. The experimental results revealed that the wear volume and specific wear rate are the functions of load, abrading distance and composition of blend. It was observed from the experimentation that the lower loading of PP into blend decreases the wear resistance. The effective wear resistance starts from higher loading of PP (30 wt.%) in the blend. The abrasive sand particles and their size played a major role in determining the wear characteristics of PA66/PP blends. Substantiate amount of rubber wheel wear contributes to the development of wear resistance. The worn surfaces are studied by using Scanning Electron Microscope (SEM) photographs.
