Title:
シートモールディングコンパウンドで使うポリマー/WUCSマット
Document Type and Number:
Japanese Patent JP2008525241
Kind Code:
A
Abstract:
A method of forming a molding mat formed bundles of reinforcing fibers and bonding materials is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The bonding materials 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 filamentizing the bonding materials, blending the reinforcement and bonding fibers, forming the reinforcement and bonding fibers into a sheet, and bonding 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.
