PCT No. PCT/SE87/00367 Sec. 371 Date Feb. 7, 1989 Sec. 102(e) Date Feb. 7, 1989 PCT Filed Aug. 21, 1987 PCT Pub. No. WO88/01363 PCT Pub. Date Feb. 25, 1988.Web material for camouflaging against electromagnetic radiation whereby the material (1) comprises several layers (4, 5, 6) against the electromagnetic radiation which is directed against the material, whereby the material is provided with a front side (2), which is intended to be turned towards a potential observer or detector, as well as a backside (3), which is intended to be turned towards an object, which is to be camouflaged. The layers consist of a first layer (6), formed of a metallic foil (4), with at least one reflective surface toward the front side (2), a second layer (5), laid on the first surface of the first layer and chosen to be of a material which is absorbent for visible light and near-infrared radiation (wave length up to approximately 2 mu m) as well as transparent for thermal infrared radiation (wave length region 3-100 mu m) as well as, on the second layer, a third layer (6), one surface of which forms said front side (2), the layer being a plastic layer (6), chosen to provide an adapted absorbtion of radiation in the region 8-13 mu m), whereby the front side (2) is textured in an embossed pattern by means of closely spaced groves (7). |
