The objective of the research is to study wear resistance characteristics of ceramics reinforced polymer composites against the solid particles impact. The composite specimens were prepared with polymer and ceramic fillers at fixed proportion of 80:20 by hand-lay-up technique. Barium titanate and calcium copper titanate were mixed in the ratios of 100:0, 0:100, 50:50, 60:40 and 40:60 to use as hybrid filler. Erosion wear test was conducted as per ASTM standard at three different velocities (48, 70 and 82 m/s) and four distinct impinging angles (30°, 45°, 60° and 90°), respectively. The experimental result shows that the striking velocity and impinging angle of sand particles have noticeable effect on wear rate. Irrespective to velocity of particle, a higher value of wear rate was obtained at 60° of impact indicating a semi brittle behavior of ceramics. The eroded surfaces of the worn samples were analyzed with SEM to ascertain the failure mechanism of the developed composites. The formation of crack and crater, wear debris, micro-plowing and micro-cutting of the erodent particles on the composite surface were the predominant mechanisms causing the erosion loss.
