Cavitation erosion tests were performed using a cavitating jet apparatus inspired by the ASTM G134 standard on a high-strength fiber reinforced composite material named Vectran. These tests were also performed on metallic materials, namely Al, SUS304 stainless steel and AlBC, to determine the effect of their elastic modulus and acoustic impedance on the erosion. The effects of the jet parameters, the standoff distance and cavitation number were also observed. Using a high speed-pressure sensor, a measure of accumulated impact energy was made: the number of high amplitude force counts decreased with the standoff distance, while the optimal erosion distance was negatively proportional to the cavitation number. The higher the intensity, the higher was the maximal mean depth of erosion rate (MDER) for all materials. The erosion rate decreased with the young modulus, but it was observed to be linearly dependent on the material's acoustic impedance.
