Abstract: In the manufacture of PVC cellular plastic, a liquid plastic mixture is admixed with fibres in an amount of at most 1 percent by weight fibres, preferably carbon fibres having a length of about 1 cm, which fibres are distributed in the expanded cellular plastic isotropically with respect to both position and alignment. The cellular plastic is effective to dampen electromagnetic radiation within the radar range to at least 1-3 dB per cm.

Abstract: PCT No. PCT/SE94/00325 Sec. 371 Date Jan. 4, 1995 Sec. 102(e) Date Jan. 4, 1995 PCT Filed Apr. 13, 1994 PCT Pub. No. WO94/24510 PCT Pub. Date Oct. 27, 1994.A camouflage material having radar screening properties is comprised of a warp-knitted fabric, so-called Raschel fabric, which includes yarn into which metal fibres have been spun. The yarn is laid with a lay-out technique such that the sum of the extensions of the yarn will be generally the same in each direction in the plane of the fabric. The fabric is suitably stabilized with a sheet that lacks metal fibres, which may either be a yarn layer in the warp-knitted fabric or a through-knitted fabric, preferably a nonwoven fabric coated with a reflective metal layer.
