FIBER-REINFORCED POLYMER COMPOSITE BODY AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sizing composition and a method for using the same.SOLUTION: Provided is a sizing composition for a glass fiber used for a reinforced polymer composite body produced by a reaction treatment technique, and a method for using the same. The embodiment in this invention refers to a sizing composition for a glass fiber used for a reinforced polymer composite body produced by the reaction treatment technique. Upon performing the reaction treatment technique, the some embodiments of the sizing composition in the invention do not disturb the polymerization of a polymer precursor such as a monomer and/or an oligomer in the production of the glass fiber-reinforced polymer composite body or suppresses the disturbance to the minimum. For example, in some embodiments, the sizing composition in this invention does not disturb anionic polymerization of the lactam in the production of the glass fiber reinforced polyamide composite body to the polyamide or suppresses the disturbance to the minimum.
