LIGHT-RESIN TRANSFER MOLDING APPARATUS FOR FIBER-REINFORCED PLASTIC

摘要

PURPOSE: A resin transfer molding method of fiber reinforced plastic by using upper and lower molds is provided to maintain a state what the upper and lower molds adhere by vacuum adsorption and to increase the production speed and productivity because only upper and lower molds of each module can be put in heating and drying processes. CONSTITUTION: A resin transfer molding method of fiber reinforced plastic by using upper and lower molds comprises a lower mold (10), an upper mold (20), a resin injecting valve, and one or more vacuum absorbing valve. The upper mold is connected to the top of the lower mold in a complementary shape and forms the vacuum groove. The resin injecting valve injects the resin inside a space formed as the upper and lower molds are engaged. The vacuum absorbing valve is installed to remove the air inside the vacuum grooves and the space.
