Abstract: The versatile applications of composite materials in different concerned mechanical processes at different environmental conditions, the damage due to striking of solid particles on T-glass fibre reinforced polyester is analysed under this study. The non-uniform geometrical shaped silica sand (SiO₂) particles (300-355 µm, 355-500 µm, and 500-600 µm) are selected as erodent. During test, impingement angles 15°-90°, impingement velocity 30-50 m/sec and standoff distance 15-25 mm at ambient temperature are considered. Results reveal that the maximum erosion of targeted composite is found at 60° impingement angle which indicates the semi-ductile characteristics of test sample. The eroded surfaces exhibit micro-cracking, micro-cutting, ploughing and pulverisation at 60° impingement angle. The average roughness 5, 50 and 100 µm is obtained for 30°, 60° and 90° impingement angles, respectively. The surface characterisation is done by SEM and 3D SEM analysis.

Keywords: T-Glass fibre reinforced polyester; erosion rate; operating parameters; SEM.
