Erosion Wear Behavior of Natural and Industrial Material for Polymer Matrix Composite by Using Taguchi Analysis

Abstract

The behavior of the erosion wear for samples manufactured by hand layupmethod of epoxy-supported fiberglass, eggshells and calcium carbonate particles were investigated.The test was performed in accordance with the experimental designs Taguchi (L 9) MINITAB (19) to select samples that have the resistance to erosion under the influence of factors. The erosion rate was assessed under the influence of three factors: weight fraction (2% to 8% eggshells and CaCO3particles), sand size (450, 650, 850 μm) and angles (30º, 60º, 90º) with a fixed face distance of 30 cm, 10 hours and a flow rate of 45 L/min. The results revealed that the rate of erosion is lower for samples consisting of enhanced epoxy resins (eggshellmolecules and CaCO3) with chopped fiber glass compared to unfilled samples. Also from these results, it should be noted that the maximum erosion rate was when the weight fraction (2%), the sand size of 850 μm and the angle of 90º, while the minimum rate of erosion was when weight fraction (8%), sand size 650 μm and 30º angle. In this work, the sample of composite materials behaves in a semi-ductile manner
