The invention relates to a fiberglass/PP composite fiber cloth assisting resin transfer molding (RTM) process method and a molding mold. The adopted mold comprises a lower mold, foam, a sealing rubberstrip, a glue injection opening, an upper mold and a vacuumizing opening. In a process, fiberglass and PP material are woven into composite fiber cloth according to required gram weight first, then needed carbon fibers or fiberglass cloth are/is laid on the surface of a mold cavity, then the fiberglass/PP composite fiber cloth is laid, the foam processed through computer numerical control (CNC) is put in, and then according to symmetrical laminates, fiberglass/PP composite fiber cloth, carbon fibers or fiberglass cloth are laid. Finally, mold assembly, vacuumizing and resin injection are conducted, after product solidification, the molding mold is opened, and a product is taken. According to the fiberglass/PP composite fiber cloth assisting resin transfer molding (RTM) process method andthe molding mold, the fiberglass/PP composite fiber cloth is adopted, PP felt and the foam are attached during material laying, the PP felt is fluffy, thus channels are provided for resin flowing, theproblem of uneven resin flowing on the surface of the foam is solved, the foam does not need slotting or punching, and machining cost of the foam is lowered greatly.
