“…The conducted experiments confirmed the presumption based on the works of authors [1,4,6,11,12] who claimed that the inclusion of filler in the matrix of epoxy resin increases hardness and resistance to abrasive wear. The composite porosity was confirmed, the occurrence of air pores influences the mechanical properties of the composite in the negative way.…”

“…Similar results were achieved by Basavarajappa et al [5], who describe a significant positive influence of SiC micro-particles on the resultant three-body abrasive wear resistance of the polymeric matrices. Mohan et al [6] used in their experiment also Si particles, they describe the improvement of tribologic properties of the polymeric composites filled with the particle size of the 20 ÷ 25 µm. Valášek [7] uses in his experiments iron metal chips from processes of milling and machining for increasing an abrasive wear resistance of reactoplastics.…”

Recycling of corundum particles - two-body abrasive wear of polymeric composites based on waste

Original scientific paperRecycling of all materials should be supported by modern society. Material recycling is one of the most important ways of dealing with waste. One of material recycling possibilities is an inclusion of waste into primary matrices. A suitable ratio and a combination of waste particles influence in a positive way mechanical properties of the material in which they are dispersed and they decrease its price. An example of the mentioned material recycling is a dispersion of corundum waste particles in the polymeric matrix. The combination of these types of matrix and filler gives birth to new polymeric particles composite -creates a qualitatively brand new material. As most important characteristics of the polymeric particle composites, one often lists resistance to abrasive wear, hardness, impact resistance and strength and, last but not least, their cost. This article deals mostly with the two-body abrasive wear resistance and hardness of polymeric particle composites with the waste Al2O3 as filler and two-component epoxy matrix. Keywords: corundum; epoxy resin; hardness; porosity; tribology Recikliranje čestica korunda -abrazivno trošenje između dva tijela od polimernih kompozita na temelju otpadaIzvorni znanstveni članak Moderno bi društvo trebalo podržavati recikliranje svih materijala. Recikliranje materijala jedan je od najvažnijih načina tretiranja otpada. Jedna od mogućnosti recikliranja materijala je uključivanje otpadnih materijala u primarne matrice. Odgovarajući omjer i kombinacija otpadnih čestica na pozitivan način utječu na mehanička svojstva materijala u kojem su raspršene, a smanjuju mu i cijenu. Primjer recikliranja spomenutog materijala je disperzija čestica otpada korunda u polimernoj matrici. Kombinacija takvih vrsta matrica i punila dovodi do novog kompozita polimernih čestica -stvara kvalitativno sasvim novi materijal. Kao najvažnije značajke kompozita od polimernih čestica često se navode otpornost na abrazivno trošenje, tvrdoća, otpornost na udar i čvrstoća, i zadnje, ali ne manje važno, cijena. Rad se uglavnom bavi otpornošću na abrazivno trošenje između dva tijela i tvrdoćom kompozita od polimernih čestica s otpadnim Al2O3 kao punilom i dvo-komponentnom matricom od epoksidne smole.

“…Sapathy and Bijwe (2002) used in his experiments corundum of size 40-100 µm for the improvement of wear resis-tance (three body abrasion) -it was achieved also by Basavarajappa et al (2010), who substituted corundum for silicon carbide (SiC). These results were confirmed also by Mohan (2012), who noticed the increase of polymeric composites tribological properties caused by the microparticles presence. Inorganic microparticles can improve not only tribological properties.…”

Valášek P., Brožek M. (2015): Microparticle composites on the basis of scrap utilizable in the field of agricultural production. Res. Agr. Eng., 61: 92-97.For renovation of functional surfaces of machines and devices for agricultural production it is possible to use, in addition to conventionally used methods, polymers with fillers -composites. The presence of microparticles in the polymeric matrix improves substantially the abrasive wear resistance and hardness. This contribution describes tribological properties of epoxy resin filled with chips of ferrous metals -the change of volume losses increase in dependence on the pressure increase (load) having effect on the worn surface. From the carried out experiments the considerable decrease of filled resin losses is evident compared with the resin without filler. At the same time the exponential increase of volume losses with the increased load was quantified in the course of tribological tests.

“…Adding microparticles also affects the thermal properties of the primary material. Mohan et al (2012) in their experiments used particles of graphite and silicon carbide as a filler and their presence led to an increase of the two-body and three-body abrasion resistance. Polymeric materials can be used in agriculture for the construction of floor coverings in forage areas where, in addition to excellent durability and resistance to wear and tear, they excel in their resistance to environmental deterioration garnet (Valášek, Müller 2012b).…”

Valášek P., Kejval J., Müller M., Cieslar J. (2015): Influence of two-body abrasion and heat intensity on metal and non-metal materials used in agriculture. Res. Agr. Eng., In the agro-complex, as well as in other sectors, the use of polymeric materials is one possible way forward in the innovation and development of machines and their parts. However, machine products place high demands on the materials from which they are made. Polymeric materials are currently able to compete in certain areas where metallic material would traditionally be used; however, one of their limiting characteristic is their ability to withstand elevated temperatures. This paper describes the hardness of polymeric materials when influenced by heat, generated during the double body abrasion. The paper also describes the abrasive wear of both polymers and polymeric composite systems, as well as cast iron, used in agricultural production. Heat intensity during the two-body abrasion results in a 28% fall of the composite systems hardness, to 18% fall of the Polyamid 6 hardness and to 13% fall of the Murtfeld hardness.Keywords: abrasive wear; composite systems, epoxy resin, polymers; temperature In recent years, industry has seen an increase in the production of plastic products in an attempt to replace the conventionally used metallic materials. One of these sectors is agriculture. The use of polymers have considerable advantages to the agricultural industry, they are easy to mould, resistant to corrosion and environmental deterioration. They have an ability to temper vibrations, low density and are cost-effective. In a specific application of various materials, particularly polymeric materials, it is necessary to consider the considerable dependence on temperature (Parry, Tabor 1973).Abrasive wear occurs when a specimen comes into contact with the abrasive material. The motion of the specimen on the abrasive material creates friction and part of this mechanical energy is converted into heat. The effects of heat at varying intensity can affect the characteristics and composition of many materials.Polymeric materials predominantly transfer heat through the vibratory motion of atoms while metallic materials transfer heat through the kinetic energy of electrons. It is for this reason that polymeric materials are usually of lower thermal conductivity, increasing temperatures create a downward effect on the yield strength of thermoplastic materials. This is evident, although not so obvious, in metallic materials. The prevailing characteristic of chemical bonds in polymeric materials results in their higher thermal expansion compared with metallic materials (Vojtěch 2010).
