PURPOSE: To laminate a skin material without spoiling lightweight property, heat resistance, etc., and without application of an adhesive and drying process by laminating a sheet-like material with fine penetration holes consisting of a heat-resistant rigid resin layer and a heat-activated resin layer on one outside of a mat-like material wherein an inorg. fiber and a thermoplastic resin fiber are main materials so as to bring the rigid resin layer on the mat-like material side. CONSTITUTION: At least on one outer side of a mat-like material as a heat-formable core material wherein an inorg. fiber and a thermoplastic resin fiber are main materials, a sheet- like material consisting of a heat-resistant rigid resin layer with a m.p. being higher than that of the thermoplastic resin fiber and a heat-activated resin layer with only one peak of crystal m.p. is formed and as fine penetration holes are provided in the sheet-like material, there is no possibility of spoiling lightweight property, heat resistance and shielding properties of air permeability and as air retention is not generated during compression process, there exists no recessed part on the surface. In addition, it is possible to laminate the skin material without coating and drying processes of an adhesive for laminating the skin material and when the skin material is adhered with the core material, as the surface of the heat-activated resin layer can be brought into direct contact with the skin material, it is possible to laminate the skin material under a condition where adhesiveness is kept excellent. |
