EFFECT OF NONWOVEN TPU/CNF TO GLASS FIBER/EXPOXY COMPOSITES ON SOLID PARTICLE EROSION RESISTANCE

Abstract

Abstract: The excellent wear resistance of nonwoven thermoplastic polyurethane (NTPU)was chosen as shielding structure. Vacuum assistant spray method was used to fabricate the NTPU/carbon nonfiber (NTPU/CNF) composites,the GF reinforced epoxy (EP) composites toughened by CNF/NTPU was fabricated via resin transfer molding (RTM) process, meanwhile the mechanical properties and solid particle erosion resistance of composites were measured and compared to EP fiber reinforced plastics (FRP). The results show that, compared to FRP, one layer of 0.1 mm NTPU made the tensile strength of the NTPU/CNF/GF/EP composites decrease about 10%, and the solid particle erosion resistance increase by 8 times. Meanwhile, ~500 μm of eroded particles exhibited a maximum erosion rate after 30 seconds of erosion at distance of 76 mm from the spout and impingement angle of 90°.
