Title:
FIBER-REINFORCED MOLDING MATERIAL AND MOLDED ARTICLE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/213414
Kind Code:
A1
Abstract:
A fiber-reinforced molding material having as essential ingredients thereof a vinyl ester resin (A), an unsaturated monomer (B) having a flash point of at least 100°C, a polyisocyanate (C), a polymerization initiator (D), and carbon fiber (E) having a fiber length of 2.5–50 mm. The fiber-reinforced molding material is characterized by the ratio (3,490 cm-1/3,340 cm-1) between the transmittance at 3,490 cm-1 and 3,340 cm-1 in a FT–IR ATR measurement being 1.01–1.06. This fiber-reinforced molding material has excellent handling and flexibility, including the work environment during molding work, molding material film peeling characteristics, and tackiness, and molded articles having excellent physical properties such as bending strength, etc., can be obtained. As a result, this molding material can be suitably used in automobile members, railway vehicle members, aerospace machinery members, ship members, housing equipment members, sports members, non-motorized vehicle members, construction and civil engineering members, and cases for OA devices, etc.
