Title:
FIBER-REINFORCED RESIN PREPREG AND METHOD TO REINFORCE OR REPAIR AN OBJECT
Document Type and Number:
Japanese Patent JP2018048231
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin prepreg that resists being displaced at the time of thermal curing after attached to a reinforcement or repair object, and a method to reinforce or repair an object using the same.SOLUTION: A fiber-reinforced resin prepreg has a thermosetting resin composition and a fiber. The thermosetting resin composition shows a lowest viscosity ηmin (Pa s) at a temperature T(°C), and a viscosity ηk(Pa s) higher than the lowest viscosity ηmin at T-10 (°C); the lowest viscosity ηmin is 200 Pa s or more; and the difference between the lowest viscosity ηmin and the viscosity ηk is 1 Pa s or more.SELECTED DRAWING: Figure 3
