This research focuses on the preparation of biochar and its usage as a novel filler and reinforcement against polyester composite manufacturing. Biochar was extracted from the cashew nut waste by undergoing pyrolysis process. Among the various polymer family available, unsaturated polyester resin was used as a matrix material whereas novel biochar filler was used as reinforcement. The composites were fabricated using solution dispersion method. Biochar of varying weights (5%, 10% and 15%) were taken for this study. The prepared specimens were subjected to erosion study using an air jet erosion test rig. Erosion studies have been performed for a fixed time of 4 min and fixed erodent discharge rate of 3 g/min with varying parameters, such as impact angle of 300, 600 and 900; velocity of 72, 100 and 129 m/s. The erosion failure mechanism of the prepared composite was also discussed for the above-selected parameter briefly. The reuse of cashew nut waste drastically reduces the environmental pollution caused due to its disposal.
