Abstract
The erosion resistance of fiber reinforced plastic (FRP) composites becomes to be significant while FRP materials are applied in erosive environments. It is demanded to improve erosion resistance of the FRP with high strength. The erosion resistance of the FRP used high strength polyethylene fiber (DF) is better but more expensive than carbon fiber (CF). To realize high cost performance FRP, in this study, the hybrid structure FRP was developed by the use of high strength polyethylene fiber for outside lamina and CF for inner layers. The erosion behavior and bending properties of DF/CF-hybrid FRP were compared with CFRP and GFRP. The results confirmed that DF/CF-hybrid composites exhibited high strength and superior particle erosion resistance. The decrease of mechanical strength after a erosion of the hybrid FRP was smaller than CFRP.
