Abstract
Polymers and their composites are widely used for their specific properties. This paper deals with composite materials based on Jatropha Oil Cake. The research was focused on influence of a mass concentration of Jatropha Oil Cake, as the filler in epoxy adhesive, on hardness and abrasion resistance. In the experiments various mass concentrations of Jatropha Oil Cake from 5 to 30% were used. Composite materials were subjected to measurement of Shore D hardness and abrasion resistance of the three-point method according to ASTM - G65. The results were analysed by statistical method ANOVA. Moisture of filler was 4.59 ± 0.22% WB. Results show that composite materials have higher weight loss than the matrix if free abrasives (fraction F60) were applied. When the free abrasives F400 were used, composite material showed comparable results with the matrix. Using of filler had no effect on changes of hardness according to Shore D. The advantage of composite systems based on Jatropha Oil Cake is utilization of waste from the presswork process that is difficult to use in the future. For example it cannot be used as a feed for animals.
