REINFORCING MATERIAL FOR HYBRID FIBER REINFORCED POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a hybrid FRP reinforcing material designed as a reinforcing material for a structure to be manufactured with concrete so that the structure is softly destroyed. SOLUTION: The reinforcing material is provided for the structure including a fiber reinforced polymer body arranged to wrap an internal core material. The internal core material is formed into a hollow tube having yield strength lower than the fiber reinforced polymer body. The fiber reinforced polymer body is arranged around the internal core material to wholly wrap the internal core material in a spiral form using twisted yarns of fiber reinforced polymer materials.
