High-density polyethylene(HDPE) is a widely used thermoplastics due to its high strength and easy processing. Carbon fiber(CF) is attracting attention as a reinforcing filler owing to its lightweight and excellent mechanical properties. Accordingly, CF-reinforced thermoplastic composites that combine good mechanical performance and easy processability are being used in various industries such as automobiles. In this study, to attain CF-reinforced thermoplastic composites with highly improved mechanical and thermal properties, poly(ethylene-co-glycidyl methacrylate)(PEGMA) was selected as a compatibilizer for improving the interfacial adhesion between HDPE and CFs, and the electron beam(EB) irradiation process was adopted for inducing a crosslinking reaction of the thermoplastic matrix. For these purposes, a series of HDPE/CF composites with PEGMA compatibilizer were manufactured through melt-compounding and injection molding. The composites are then irradiated with different EB doses. |
