Claim Text:
1. A production method for a multilayer lining for thermal and sound insulation, comprising the steps of: blending reinforcement fibers with a polyamide matrix material, in the form of fibers, flakes or powder, to form a blended web; layering the blended web inside a mould with at least one additional layer forming a stacked multilayer material, where each of the additional layers is an open cell foam layer, a heat reflective layer, or a further blended web; treating with pressurized saturated steam the stacked multilayer material in the mould, the pressurized saturated steam having a temperature sufficient to melt the polyamide matrix material in each blended web, the melted polyamide matrix material consolidating the reinforcement fibers in each blended web into a porous reinforcement layer, while simultaneously laminating the layers of the stacked multilayer material into a multilayer lining.
