METHOD FOR MANUFACTURING HOLLOW REINFORCED RESIN COMPOSITE MATERIAL ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for easily manufacturing a hollow reinforced resin composite material article by using a preform. SOLUTION: A thermoplastic resin binder is used for bonding reinforcing fibers each other, increasing strength and facilitate manufacturing. The method related to this invention comprises steps of positioning the preform 10 with an inflatable core 14 in a mold 28, compressing the core 14, heating the mold so as to melt the thermoplastic binder and to spread it in the preform, and bonding the reinforcing fibers. A finished article is removed from the mold after it is cooled to obtain a hollow molded article. The inflatable core may be removed from the finished article and reused or may become a part of the finished article without being removed. COPYRIGHT: (C)2003,JPO
