Title:
EPOXY RESIN COMPOSITION, PREPREG, CARBON FIBER REINFORCED COMPOSITE MATERIAL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2019167429
Kind Code:
A
Abstract:
To provide a resin composition, wherein, a reinforced fiber base material can be sufficiently impregnated with the resin composition, handleability of a prepreg is high at room temperature, and excessive flow is suppressed in the prepreg during molding; a prepreg obtained by impregnating the reinforced fiber base material with the resin composition; and a method for producing FRP using the prepreg.SOLUTION: The problem is solved by blending two curing agents having different curing initiation temperatures, and viscosity increase particles that swell at a predetermined temperature for viscosity increase in an epoxy resin composition constituting a prepreg, and controlling the viscosity of the epoxy resin composition.SELECTED DRAWING: None
