HEAT-FOAMABLE FILLING REINFORCEMENT AND REINFORCED CLOSED-SECTION STRUCTURAL-MEMBER STRUCTURE MAKING USE OF THE SAME

摘要

This invention relates to a reinforced closed-section structural-member structure making use of a heat-foamable filling reinforcement. The structure has been formed by connecting plural closed-section structural members (11-15) together. These closed-section structural members (11-15) are internally filled with a heat-foamed filling reinforcement (1) which comprises an epoxy resin material, a synthetic rubber material and a thermoplastic resin material as components.
