Being the structure modulo stamper bull sheet, the lightweight stamper bull sheet and its production

摘要

PROBLEM TO BE SOLVED: To provide a lightweight stampable sheet being excellent in specific strength, specific rigidity, being lowly irritating to the skin and being excellent in handleability. ;SOLUTION: There are provided a papermaking process stampable sheet being a fiber-reinforced thermoplastic resin sheet based on a thermoplastic resin and reinforcing fibers, wherein the reinforcing fibers comprise inorganic fibers and organic fibers, the temperature which is either the melting point or the decomposition temperature of the reinforcing fibers and is the lower one is higher than the melting point of the thermoplastic resin and a lightweight stampable sheet being a fiber-reinforced porous material based on a thermoplastic resin and reinforcing fibers, wherein the reinforcing fiber comprises an inorganic fiber and an organic fiber, and the temperature which is either the melting point or the decomposition temperature of the reinforcing fiber and is the lower one is higher than the melting point of the thermoplastic resin.;COPYRIGHT: (C)1998,JPO
