A method of forming a molding mat (295) formed bundles of reinforcing fibers and bonding materials is provided. The reinforcing fibers (200) are preferably- wet use chopped strand glass fibers (WUCS) . The bonding materials (210) may be any thermosetting material having a melting point less than the reinforcing fiber. The molding mat may be formed by partially opening the wet use chopped strand glass fibers and f ilamentizing the bonding materials, blending the reinforcement and bonding fibers, forming (270) the reinforcement and bonding fibers into a sheet, and bonding (290) the sheet. During bonding, the sheet is heated to a temperature above the melting point of the bonding fibers but below the temperature of the glass fibers . The molding mat thus formed may be used as a reinforcement material in sheet molding compounds. |
