1. A carbon fiber forming raw material (Z) as a prepreg including sizing agent-coated carbon fibers coated with a sizing agent and a thermosetting resin, or
a carbon fiber forming raw material (Y) as a forming material including sizing agent-coated carbon fibers coated with a sizing agent, the forming material having a woven fabric form or a braid form, wherein the sizing agent comprising: a component (A) including
an epoxy compound (A1) having two or more epoxy groups and/oran epoxy compound (A2) having one or more epoxy groups and at least one or more functional groups selected from a hydroxy group, an amido group, an imido group, a urethane group, a urea group, a sulfonyl group, and a sulfo group; and a component (B) being contained in an amount of 0.1 to 25 parts by mass relative to 100 parts by mass of the component (A) and including at least one reaction accelerator selected from the group consisting of: a component being a tertiary amine compound and/or a tertiary amine salt (B1) having a molecular weight of 100 g/mol or more, a component [b] being a quaternary ammonium salt (B2) having a cation site represented by(where each of R1 to R4 is a C1-22 hydrocarbon group, the hydrocarbon group optionally has a hydroxy group, a CH2 group in the hydrocarbon group is optionally substituted by —O—, —O—CO—, or —CO—O—) or(where R5 is a C1-22 hydrocarbon group, the hydrocarbon group optionally has a hydroxy group, and a CH2 group in the hydrocarbon group is optionally substituted by —O—, —O—CO—, or —CO—O—; each of R6 and R7 is hydrogen or a C1-8 hydrocarbon group, and a CH2 group in the hydrocarbon group is optionally substituted by —O—, —O—CO—, or —CO—O—), and
a component [c] being a quaternary phosphonium salt and/or a phosphine compound (B3). |
