Abstract

Abstract: Numerical simulation has been carried to study the influence of impingement angle due to air borne particle erosion on glass fiber reinforced polymer (GFRP) composites and validated experimentally. In the experiment setup, air-jet erosion test–rig is used, in which erodent particles are striking at different impingement angles of 15°, 30°, 45°, 60°, 75° and 90° with impact velocity of 25 m/s. For the computational fluid dynamics modelling of erosion behavior, the Discrete phase Model (DPM) for tracking the particle and oka's model for composite erosion are used in ANSYS Fluent. The results of steady state experiment show that erosion rate of glass fiber reinforced composite is low at 15° impingement angle and maximum value is found in between 30° to 90° impingement angles, which reveals semi ductile behavior of fabricated composite. The Numerical simulation erosion response on glass fiber reinforced polymer composite at different impingement are in good agreement with experiments.
