Effect of Impingement Angle and Erodent Temperature on Erosion Wear Behavior of Bamboo Fiber Reinforced Epoxy Composites

Abstract

For a composite material, its surface damage by solid particle erosion depends on many factors. One of the most important characteristics of erosion is the variation of erosion rate with impingement angle. Determining the effect of the impingement angle on erosion is the most sensitive way of studying the mechanism of erosion. The erosion rate is also greatly affected by the erodent temperature. In the present work a series of systematic erosion tests were carried out to investigate the influence of impingement angle and erodent temperature on erosion mechanisms of bamboo fiber reinforced epoxy composites using an erosion test rig. Bamboo fiber reinforced epoxy composites are fabricated using red mud, copper slag, Al2O3 and SiC particles as filler materials. The erosion rates of these composites have been evaluated at different impingement angles (15-90°) and at different erodent temperatures (30-60°C) and the conclusions drawn from the above investigation are discussed.
