ね備えたものはなくその実現に苦慮していた。[Prior Art and its Problems] Conventionally, a lining material for automobiles, particularly a ceiling material, is used as a core material of glass fiber, polystyrene, corrugated board,
Although many felt-based materials are used, generally, for ceilings, many excellent performances such as sound absorption, heat insulation, workability and dimensional stability are required. However, there was no one that fulfilled the requirements for a ceiling lining material, and it was difficult to realize it.
そこで近時、吸音性,機能性,軽量性,組立容易性に

は、その形状の現出が不充分であった。Polyurethane-based foams have a good foam structure in which the shape of the foam is open-celled, and if possible, it is considered that the foam cells are ideally non-uniform and complex shapes, rather than uniform shapes. Since the shape does not have self-holding property, the polyurethane foam itself is treated with a thermosetting resin such as epoxy, polyester, melamine, or an isocyanate, or various non-woven fabrics, glass paper, and various film sheets are used on the front and back of the foam. Or a method of forming a sandwich structure by pasting and laminating in a state of being impregnated with resin, both of which used continuous polyurethane foam as the core material, and thus the shape retention was slightly inferior and the shape with deep drawing property was used. In the molding of, the appearance of the shape was insufficient.
