Production process for a moulded multilayer lining |
摘要 |
Production method for a multilayer lining for thermal and sound insulation with the steps of blending reinforcement fibers and polyamide matrix material, in the form of fibers, flakes or powder, and forming a web of said blend; layering said blended web and at least an additional layer chosen from an open cell foam layer, a heat reflective layer, or another of said blended web inside a mould; treating the stacked multilayer material with pressurized saturated steam, such that the polyamide matrix material in the blended web is melting at a temperature under steam pressure that is lower than the melting temperature of the polyamide matrix according to DSC, thereby binding the reinforcement fibers together thus consolidating the blended web forming a porous reinforcement layer, and all layers of the multilayer are laminated together. |
