Wear response of chopped E-glass fiber reinforced epoxy with various volume fractions and concentration of (ZrO2) Nano particle

Abstract

In this study epoxy resin was reinforced by chopped E-glass fiber at different volume fraction (10, %20, %30% and 40%) with ZrO2 Nano particles in grain size (55 nm) that was added with different quantities (1%, 1.5 % and 2 %wt.) and chopped fiber glass composites with volume friction10 % to study wear response in this conduction. stirring and ultrasonic mechanical mixing is used to fabricate a mixing component for producing reinforcement mixtures. Mechanical tests such as adhesive wear, Charpy impact strength, shore D hardness, were carry out. As a result, composites with filler material have higher strength than composites that are not packed. The wear test was carried out with various time loads, the apparatus pin on disk being used to research the adhesion wear specification. The tests were carried out on a group of specimens over a range of time (5to 15 min) and loads (0.5 to 2 kg). The results of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) analysis, the micrographs and EDS, SEM showed that composites were efficiently converted to filler material used in dentistry and tissue engineering. The result show that the hardness for 10 wt% composite is higher compared to other ratios and this result effected on wear response, ZrO2 Nano particles were contributed in enhancement wear rate. The best result of composite has ZrO2 at percentage 1%.
