The aim of the study was to develop environmentally friendly, low-cost, and highly erosion-resistant composites using rubber particles recycled from waste tires as reinforcement. The effects of impingement angle, weight fraction, and particle size were investigated. While neat epoxy exhibited a maximum erosion rate at 30 degrees, rubber/epoxy did so at 15 degrees, or in the range of 15 degrees-30 degrees. The erosion behavior of epoxy became more ductile as a result of rubber reinforcement. Rubber particle reinforcement significantly reduced the maximum erosion rate, especially at 30 degrees. At this angle, the erosion rate of neat epoxy was 1.88 x 10-4 g/g, while that of the composite with the highest resistance was 1 x 10-4 g/g. The increases in weight fraction and particle size enhanced erosion resistance. Statistical analysis revealed that their individual effects were close. The regression model exhibited high accuracy with coefficients of R2 (99.29%) and R2(adj) (98.10%), confirming its reliability. Its predictive capability was measured as R2 (pred) at 91.88%. The erosion efficiencies were below 1%. It confirmed the ductile erosion mechanism. The decrease in erosion efficiency provided high erosion resistance. Morphological analysis was conducted using scanning electron microscopy. The erosion-resistant rubber/epoxy composites are recommended for use as coating.Highlights Reuse of waste tires as a reinforcement is possible. Rubber particles significantly enhanced erosion resistance. The composites exhibited highly ductile erosion behavior. Erosion rate decreased with increasing in weight fraction and particle size. Morphological examination revealed that erosion damage was not severe.
