Patent number: 6607798Abstract: Center cores are formed by extrusion-molding ABS resin. Seven pieces of the center cores, which are juxtaposed to each other in the horizontal direction, are supplied by a pultruder, and reinforcing long-fibers impregnated with an unsaturated polyester resin are allowed to pass through dispersion guides and squeezing nozzles, to thus squeezing-mold a fiber-reinforced composite hollow structure having FRP made legs. A final squeezing nozzle is disposed in a cross head die through a cooling jacket, and the hollow structure thus molded is allowed to pass therethrough to be covered with the ABS resin in a state in which the outer periphery of the hollow structure is heated. The hollow structure thus covered is subjected to cooled-sizing through a plurality of horizontal and vertical pairs of rollers, and then cured in a hot curing tank. The surface covered with the ABS resin is subjected to a surface-treatment of imparting irregularities for giving an antislipping function to the surface.Type: GrantFiled: July 20, 2000Date of Patent: August 19, 2003Inventors: Toru Watanabe, Shigehiro Matsuno, Naoyuki Kondo, Takayuki Hoshino, Hidenori Nomura
