Abstract
Cavitation erosion tests were carried out on fiber-and particle-reinforced composites for repairs; four GFRP(Glass Fiber-Reinforced Plastic)test pieces with different laminate structure and four PRP(Particle-Reinforced Plastic)test pieces with different composite structure, and the relationship between cavitation erosion resistance and structural property was examined. Resistance to cavitation erosion for GFRP test pieces was higher than that of matrix resin of GFRP without glass fiber, Cavitation resistance of GFRP decreased with Shore hardness. Cavitation-erosion resistance of PRP test pieces was lower than that of GFRP test piece with top and surface coating.
