Abstract

Composite materials have many applications at different mechanisms in industry. The erosion characteristics of new combinations of ebonite reinforced with carbon fiber were analyzed in this study. Randomly-shaped sand (SiO2) particles of various sizes (300–355, 355–500, and 500–600 μm) were selected erosive element. Tested conditions such as impact angles between 15 and 90°, impact velocities between 30 and 50 m/s, and stand-off distances 15–25 mm at surrounding room temperature were maintained. The highest level of erosion of the tested composite was obtained at 60° impact angle, which signifies the semi-ductile behavior of this material. Erosion showed an increasing trend with impact velocity and decreasing nature in relation to stand-off distance. Surface damage was analyzed using SEM to examine the nature of the erosive wear mechanism.
