Abstract
PURPOSE: To produce the subject sheet excellent in thermoforming properties, heat resistance, mechanical strength, etc., at a low cost by heating a matlike material formed of fibers, etc., comprising a thermoplastic resin and inorganic fibers at a specific temperature, heating the resultant material at a specified temperature together with the release of compression and cooling the heated material. CONSTITUTION: A matlike material comprising fibers or a powder composed of a thermoplastic resin (preferably polyethylene, etc.) and inorganic fibers (e.g. glass fibers) is heated at a temperature of the melting temperature of the thermoplastic resin or above (preferably heated at a higher temperature than the melting temperature by 10-70 deg.C for 1-10 min), subsequently compressed (preferably under 3-4 kg/cm<2> pressure) and then heated at a temperature of the melting temperature of the thermoplastic resin or above (preferably heated for 20 s to 2 min) together with the release of compression to recover the thickness. The resultant material is further cooled to produce the objective sheet suitable for an automotive ceiling material.
