Document Type and Number:

WIPO Patent Application WO/2011/092962

Kind Code:

A1

Abstract:

Disclosed are: a sizing agent for a carbon fiber, which is applicable to various molding methods and can be used for the production of a molded article that has a good balance between excellent strength and weight reduction; a carbon fiber which is surface-treated with the sizing agent; a method for producing the carbon fiber; and a molding material and a molded article, which contain the carbon fiber. Specifically disclosed are: a sizing agent for a carbon fiber, which contains a moisture curable polyurethane (A); a surface-treated carbon fiber (C) which has, on the surface of a carbon fiber (c), a coating film that is formed by moisture curing the moisture curable polyurethane (A) contained in the sizing agent for a carbon fiber; a method for producing a surface-treated carbon fiber (C); a molding material which is characterized by containing a curable resin (D), a polymerizable unsaturated monomer (E) and the carbon fiber (C); and a molded article which is obtained by molding the molding material.
