Solid Particle Erosion of Luffa cylindrica Fiber Reinforced Polymer Composite

摘要

Experiments were carried out to study the effects of impingement angle and particle velocity on the solid particle erosion behavior of Luffa cylindrica fire reinforced epoxy composites. The erosive wear is evaluated at different impingement angles from 30 to 90° at three different velocities of 48, 70 and 82 m/s. The erodent used is silica sand with the size range 150-250 μm of irregular shape. The result shows semi ductile behaviour with maximum erosion rate at 45-60° impingement angles. The morphology of the eroded surfaces was examined by using Scanning Electron Microscopy (SEM).
