MATRIX RESIN COMPOSITION FOR FIBER-REINFORCED PLASTICS AND PROCESS FOR PRODUCTION OF FIBER-REINFORCED PLASTICS

摘要

The present invention is a 2-functional or trifunctional liquid diisocyanate, a chain extender of a bifunctional which contains a bifunctional polyol and the active hydrogen groups in a molar ratio of functional groups, diisocyanate: polyol: chain extender = 5.0 to 1.0: 1.0 then for a fiber-reinforced, characterized in that it contains from 4.0 to 0 the plastic matrix resin composition, and impregnating the fiber material in the resin composition, provides a process for the production of fiber reinforced plastic is cured. According to the present invention, a molded article having excellent properties such as strength and swelling property by which the thermosetting resin extends the pot life, it contains a dense fiber in the manufacture of the FRP molded product can be produced.; Fiber reinforced plastics, the matrix resin composition
