Title:
CARBON FIBER MOLDING MATERIAL, MOLDING MATERIAL, AND CARBON FIBER-STRENGTHENING COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/084669
Kind Code:
A1
Abstract:
A carbon fiber molding material is provided that exhibits excellent interfacial adhesion between the carbon fibers and a thermosetting resin, and that yields a molded product exhibiting excellent mechanical properties. The carbon fiber molding material is either (Z) a prepreg containing sizing agent-coated carbon fibers and a thermosetting resin, or (Y) a material for forming woven fabric or braided cords that employs sizing agent-coated carbon fibers. The sizing agent is characterized by containing the following components (A) and (B): component (A) is an epoxy compound having two or more epoxy groups, or two or more functional groups; component (B) is a compound containing one or more of the group consisting of a tertiary amine compound, a tertiary amine salt, a quaternary ammonium salt, a quaternary phosphonium salt, and a phosphine compound. The sizing agent is obtained by blending 0.1-25 parts by mass of the compound (B) with 100 parts by mass of the compound (A).
