Investigating the solid particle erosion behavior of H₃BO₃ / B₂O₃ / SiO₂ / Al₂O₃ reinforced glass fibre/epoxy composites and parametric evaluation using artificial intellige

In this experimental study, the erosion wear behavior of glass fibre-reinforced (GF) composite materials was examined according to ASTM G76–95. Pure/GF reinforced epoxy composite (EP) materials were chosen as the main test sample. Boric Acid (H 3 BO 3 ), Borax (B 2 O 3 ), Silicon Dioxide (SiO 2 ), and Aluminium Oxide (Al 2 O 3 ) were added to the resin as reinforcement at a rate of 15% by weight. The erosion wear rate was investigated with various impingement angles (30°, 60°, and 90°), impact velocities (≈23, 34, and 53 m/s), alumina abrasive particle sizes (≈200 and 400 μm), and fibre directions (0° and 45°). Neural network models were employed effectively to predict the influence of the reinforcements on erosive wear rate. The erosive wear rate indicated that Al 2 O 3 added GF/EP exhibited the most anti-erosive characteristics followed by silicon dioxide GF/EP and pure GF/EP however, the anti-erosive nature of GF/EP deteriorated with the addition of Borax and Boric Acid.
