Abstract

The present invention relates to adhesive coated fabrics, suitable for use in composite materials, coated on at least one outwards facing surface thereof with an acrylate adhesive, wherein the coated acrylate adhesive on said at least one outwards facing surface is less than 11 g/m² solid particles. Such adhesive coated fabrics are especially useful for the manufacturing of water or moist resistant or repellant structures such as boats, airplane components, wind turbine blades, helmets, or telephone poles.

Claims

1. Adhesive coated fabric, suitable for use in composite materials, coated on at least one outwards facing surface thereof with an acrylate adhesive, wherein the coated acrylate adhesive on said at least one outwards facing surface is less than 11 g/m² solid particles.

2. Adhesive coated fabric according to claim 1, wherein the coated acrylate adhesive on said at least one outwards facing surface is less than 7 g/m² solid particles.

3. Adhesive coated fabric according to claim 1 or claim 2, wherein the coated acrylate adhesive on said at least one outwards facing surface is less than 5 g/m² solid particles.

4. Adhesive coated fabric according to any of the claims 1 to 3, wherein the outwards facing surface is selected from the group consisting of glass fiber, aramide, carbon fibre, polymeric fibre, and combinations thereof.

5. Adhesive coated fabric according to any of the claims 1 to 4, wherein the outwards facing surface is a continuous glass fiber mat.

6. Adhesive coated fabric according to any of the claims 1 to 5, wherein the outwards facing surface is a nonwoven continuous glass fiber mat.

7. Adhesive coated fabric according to any of the claims 1 to 6, wherein the adhesive coated fabric comprises at least one thickness-providing layer of a non-woven or a knit of glass fibre and at least one strengthening layer connected thereto.

12. Composite material comprising an impregnated adhesive coated fabric according to any of the claims 1 to 7 or claim 11.

13. Use of an adhesive coated fabric according to any of the claims 1 to 7, the adhesive coated fabric according to claim 11, or the composite material according to claim 12 for the manufacture of water resistant or repellant structures.

8. Method for preparing an adhesive coated fabric, wherein the method comprises spraying less than 11 g/m² solid particles of an acrylate adhesive on at least one outwards facing surface of the fabric.

9. Method according claim 8, wherein less than 7 g/m² solid particles of an acrylate adhesive is sprayed on the at least one outwards facing surface of the fabric.

10. Method according claim 8 or claim 9, wherein less than 5 g/m² solid particles of an acrylate adhesive is sprayed on the at least one outwards facing surface of the fabric.

11. Adhesive coated fabric obtainable by using a method according to any of the claims 8 to 10.
