FOAMED RESIN CORE BUILT-IN FRP AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent the penetration of an injected resin into a core made of a foamed resin and to improve appearance and the creak sound caused by the bending of a molded object, in foamed resin core-built-in lightweight FRP. SOLUTION: The foamed resin core built-in FRP is characterized in that the surface of the core made of the foamed resin is covered with a heat-shrinkable film and a fiber base material impregnated with a thermosetting resin is laminated on the core through the film.
