Solid Particle Erosion Wear of GF∕EP Composites with Added Al[sub 2]O[sub 3

Abstract

This study has targeted to investigate wear behavior of a sort of new composite material where Al2O3 (≈150 μm) particles were added to glass fiber and epoxy resin (GF/EP) at an amount of 15% and 30%. The method used in the tests, was the one that use dry and compressed air to accelerate abrasive particles onto a specimen and from there the wear formed was investigated. Striking speed was determined with the help of a double disc method by making use of pressure difference, whereas impinging angles were set by turning the specimen holder around its axis. As a result, in this experimental study, solid particle erosion behavior of a new formed composite material was investigated and erosion rates computed where three different impinging angles (30°, 60° and 90°), three different striking speeds (23, 34 and 53 m/s) and two different fiber directions (0° and 45°) were used to enable angular aluminum abrasives with average diameter of 400 μm to bombard target specimens to undertake the tests. In addition, the s...
