Abstract:
This research work evaluates the effect of barium sulphate contents on the physical, mechanical, dynamic mechanical, and erosion wear properties of fixed glass fiber reinforced epoxy composites. Composites with 0 to 30 wt% barium sulphate were prepared by vacuum assisted resin transfer molding (VARTM) technique under controlled pressure condition. The manufactured composites were characterized for physical (density, void content, and hardness), mechanical (tensile, flexural, and inter‐laminar shear strengths), dynamic mechanical, and erosion wear properties including numerical and experimental analysis. Experimental results show that the addition of increased barium sulphate content results in increased density, void content, hardness, interlaminar shear strength, and fracture toughness of the composites, while tensile and flexural properties were found to decrease above 10 wt% barium sulphate content. Erosion results revealed that the maximum wear rate was found between the ranges of 45° to 75° impingement angle, which shows semi‐ductile nature of the composites. Moreover, computational fluid dynamic (CFD simulation by ANSYS fluent) analysis was introduced to calculate the erosive wear rate, erosion scar, and then tracking the particle trajectories in order to validate the numerical results by comparing the obtained experimental results for validation. Finally, the erosion efficiency was calculated as a function of impact velocity of the proposed particulate filled composites and eroded samples were analyzed through scanning electron microscope to observe the wear characteristics of the composites.
