Method for manufacturing curved bodies of fiber reinforced plastic

摘要

A method for manufacturing a curved fiber reinforced body of plastic material by cutting plastic impregnated fibers with a cutter, directing the cut fibers onto a rotating form and applying a plastic material to the fibers. The fibers are deposited in predetermined radial and circumferential directions to build up a proform of overlapping layers of oriented fibers as the form is rotated. The preform is shaped by compression between mating shaping forms to substantially the final molded shape. The plastic material contains a curative and is partially cured under controlled conditions after the preform is built. The preform is then preheated in an oven and molded under predetermined pressures and temperatures.
