Abstract
Official abstract text for this publication.
A composite skin material for a vehicle includes a fibrous substrate, a polyurethane resin layer provided on the front side of the fibrous substrate, and a woven fabric adhered to the back side of the fibrous substrate through an adhesive layer comprising a polyurethane resin. Openings penetrating the fibrous substrate from the front of the polyurethane resin layer are provided in the composite skin material, and an opening ratio on the front of the polyurethane resin layer is 1 to 15%. The woven fabric has a warp density of 25 to 50 yarns/25.4 mm and a weft density of 30 to 50 yarns/25.4 mm, and the mass per unit area of the adhesive layer is 15 to 100 g/m 2 . The composite skin material has air permeability of 5 to 100 cm 3 /cm 2 ·s, tear strength of 20 to 150N, and tensile strength of 50 N/cm or more.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite skin material for a vehicle, comprising a fibrous substrate, a polyurethane resin layer provided on the front side of the fibrous substrate, and a woven fabric adhered to the hack side of the fibrous substrate through an adhesive layer comprising a polyurethane resin, the polyurethane resin layer having a plurality of openings on the front thereof, wherein: a plurality of the openings are holes penetrating the fibrous substrate from the front of the polyurethane resin layer, and an opening ratio on the front of the polyurethane resin layer is 1 to 15%; the woven fabric has a warp density of 25 to 50 yarns/25.4 mm and a weft density of 30 to 50 yarns/25.4 mm; through-holes connected to the openings are formed on the adhesive layer at the positions corresponding to the openings, and the through-holes are covered with the woven fabric; the mass per unit area of the adhesive layer is 15 to 100 g/m 2 ; air permeability of the composite skin material is 5 to 100 cm 3 /cm 2 ·s; tear strengths in a warp direction and a weft direction of the composite skin material each are 20 to 150N; and tensile strengths in a warp direction and a weft direction of the composite skin material each are 50 N/cm or more. 2. The composite skin material for a vehicle according to claim 1 , wherein the fibrous substrate is a woven fabric, a knitted fabric, or a non-woven fabric. 3. The composite skin material for a vehicle according to claim 1 , wherein the fibrous substrate is a knitted fabric. 4. The composite skin material for a vehicle according to claim 1 , wherein the through-holes formed in the adhesive layer are provided only at the positions corresponding to the openings. 5. The composite skin material for a vehicle according to claim 1 , wherein the adhesive of the adhesive layer comprises a reactive hot-melt polyurethane resin as a layer which is continuous and coextensive with the woven fabric except for the openings formed on the adhesive layer.
