METHOD FOR MANUFACTURING CARBON-FIBER-REINFORCED MOLDING MATERIAL AND MOLDED ARTICLE

WIPO Patent Application WO/2023/120090

A1

Provided are: a method for accurately detecting impurities such as metal in a carbon-fiber-reinforced molding material to efficiently produce a carbon-fiber-reinforced molding material and a molded article; and a carbon-fiber-reinforced molding material and a molded article obtained by this method. The method for producing a carbon-fiber-reinforce molding material is characterized by comprising a step for inspecting a molding material for the presence of impurities such as metal using an impurity detection method based on X-ray irradiation. The production method is for a molded article characterized by being obtained by hot compression molding the carbon-fiber-reinforced molding material obtained from the aforementioned production method.
