FIBER GLASS REINFORCED PLASTIC SANDWICHES PANEL WITH A BUILT-IN FOAMED RESIN

摘要

An FRP sandwich panel having foam resins built-in is provided to have excellent durability, to have excellent insulation and heat insulation efficiencies by using foam resins as a core material, and to make mass production possible by laminating many moldings under vacuum. An FRP sandwich panel having foam resins built-in comprises foam resins(1) provided for heat insulation and insulation, and a hardened layer(2) formed by impregnating and applying glass fiber and thermosetting resins on the upper and lower parts of the foam resins and compressing under vacuum.
