Problems solved by technology

However, in conventional carbon fiber-reinforced resin compositions using vinyl ester resins, the adhesiveness between the resin component in the cured product and the carbon fibers is insufficient, so that the interlaminar shear strength of the cured product may not be sufficiently obtained.

Abstract

A composition for a carbon fiber-reinforced resin includes (A) a radical-reactive resin, (B) a radical-polymerizable unsaturated monomer, (C) a mercapto group-containing compound, (D) an imidazole compound having only one imidazole ring, and (E) an organic peroxide. The composition for a carbon fiber-reinforced resin may also include (G) a metal soap.

Description

technical field [0001] The present invention relates to a composition for carbon fiber-reinforced resin capable of efficiently curing at low temperature in a short time and capable of obtaining a cured product having good adhesion between a resin component and carbon fibers, and a carbon fiber-reinforced resin combination including the composition for carbon fiber-reinforced resin and its solidification. [0002] This application claims priority based on Japanese Patent Application No. 2016-101352 for which it applied in Japan on May 20, 2016, and uses the content here. Background technique [0003] Conventionally, as a carbon fiber-reinforced resin composition, a composition containing an epoxy resin having good adhesion to carbon fibers and carbon fibers is known. However, a carbon fiber-reinforced resin composition using an epoxy resin requires heating for curing at a high temperature and for a long time. [0004] In addition, as a carbon fiber-reinforced resin composit...
