(57) [Abstract] [PROBLEMS] To provide a vacuum and / or pneumatic thermoforming method for an air-permeable fabric of elastic fibers and thermoplastic fine particles. [Structure] (a) A bulky, porous, air-permeable, fiber-reinforced thermoplastic woven fabric containing thermoplastic fine particles is pasted with a thermoplastic film to prepare a sealed preform, and (b) sealed. A bulky reinforced composite comprising heating the preform to a temperature above the melting point of the thermoplastic particulates of the fabric, and (c) vacuum and / or pressure forming the heated preform to produce a shaped product. A method for thermoforming a material. |
