“…Satapathy et al [4] found out in their experiments that for epoxy with primary corundum filler with particle size of 40 ÷ 100 μm, the inclusion of corundum increased resistance to abrasive wear. 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.…”

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.

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.

“…From the carried out experiment the presumption of authors (Satapathy, Bijwe 2002;Basavarajappa et al 2010;Valášek, Müller 2010) was certified that the inclusion of the corundum particles decreased considerably the volume losses of the composites compared with the resin without the filler. The presumption was certified at the same time that systems with smaller filler particle size (F800, F240) will be more prone to the abrasive wearing on used abrasive cloth.…”

Filling with the micro-particles is justified at the thermoplastics as well.…”

Valášek P., Kejval J., Müller M., 2014. Epoxy resin filled with primary and secondary raw material -useable in agriculture. Res. Agr. Eng., Hard inorganic particles in the interaction with polymeric materials increase wear resistance. Also reactoplastics are suitable for filling with micro-and nano-particles for a purpose of some mechanical properties optimization. The paper compares chosen mechanical properties -hardness, wear resistance and tensile characteristics of epoxy resin filled with artificial corundum with various middle particles sizes and their ratio combination. Mentioned systems can be used in a sphere of the agricultural production at renovation of machine parts, they can serve for creating resistant layers on machines, floors and grillages at the same time. The aim of the carried out experiment is to compare the properties of reactoplastics filled with a primary and secondary raw material and to define an optimum ratio of the filler particle size relating to a given mechanical quality. The artificial corundum was chosen as the primary material, the waste corundum from the process of material mechanical treatment was chosen as the secondary one.Keywords: hardness; tensile strength; waste; wear In the sphere of animal and plant production many machines are used whose functional areas are exposed to specific types of degradation. An abrasive wear can be ranked among the most widespread types of the wear in the agrocomplex. Functional areas of machines can be renewed by classical way -overlaying. It is also possible to use polymeric particle composites when coating of such materials is fact and inexpensive and it is not necessary to have a special equipment.Reactoplastics belong to a group of polymers which create chemical bonds among single molecules at a hardening. During the hardening it comes to an interconnection of the macromolecules by transverse covalent bonds which create a reference space grid.The macromolecule setting defines properties of the reactoplastics -it influences permanent deformation in a negative way. Compared with thermoplastics the reactoplastics show higher modulus of elasticity, increased dimensional stability, they are hard and firm. The properties of the reactoplastics e.g. epoxy, polyester, phenolic and other resins are suitable for filling with micro-particles and nano-particles, these resins can serve as matrices of fibre composites at the same time. The epoxy resins are constructional adhesives which can be used at connecting of metals, glass, ceramics and other materials. They excel by good chemical resistance and by mechanical properties.The micro-particles can improve values of a tensile strength and wear resistance. The example

“…Similar type of observations was found by other researchers. [46][47][48][49] A low specific wear rate was found in benzoyl chloride treated based composite with 30 wt.% fiber loading followed by the alkali treated and untreated composite in both the Figures 3 and 4. It is evident from Figure 3 that benzoyl chloride treated fiber composites i.e., Figure 3 (c) shows the minimum specific wear as compared to untreated (Figure 3 (a)) and alkali treated composite (Figure 3 (b)).…”

The present article depicts the specific wear rate of jute fiber reinforced epoxy composites with different weight percentage of fiber loading (10, 20, 30, 40 wt. %) and different chemical treatments (Alkaline and Benzoyl chloride treatment). The three-body abrasive wear analysis was studied according to ASTM-G65 using a rubber wheel abrasion apparatus (dry sand wear tester) at room temperature by varying different factors like fiber content, abrasive particle size, normal load and sliding distance. To calculate the abrasive wear behaviour of jute/epoxy composites, the design of experiments approach based on Taguchi's orthogonal array has been adopted. Steady state result shows that with the inclusion of chemical treatment in jute fiber improved wear resistance capacity of the composites. Finally, scanning electron microscope (SEM) studies revealed the morphologies worn surface of the composites such as micro-ploughing, formation of debris, micro cracking and fiber matrix de-bonding.
