    • Textile materials having radar attenuating properties comprise a polymer enclosed scrim characterised in that the material further comprises hollows which are at least partially filled with radar attenuating material. Preferred embodiments of the invention have the scrim sandwiched between two or more polymeric layers, wherein the spaces comprise the interstices of the scrim. Suitable radar attenuating materials for inclusion in the spaces include carbon granules, carbon fibre, carbonyl iron, ferrites or metal coated microspheres, but other suitable materials will occur to those skilled in the art. Carbon fibre is conveniently used in chopped or otherwise relatively short fibre form. The textiles offer lightweight with equivalent radar attenuation performance to known textiles and may be formed such that further radar attenuating material is provided in polymeric components to provide enhanced attenuation effect.
    • 具有雷达衰减特性的纺织材料包括聚合物封闭的稀松布,其特征在于,所述材料还包括至少部分地填充有雷达衰减材料的中空部。 本发明的优选实施方案具有夹在两个或多个聚合物层之间的稀松布,其中空间包括稀松布的间隙。 用于包含在空间中的合适的雷达衰减材料包括碳颗粒,碳纤维,羰基铁,铁氧体或金属涂覆的微球,但是本领域技术人员将想到其它合适的材料。 碳纤维方便地用于短切纤维或其他相对较短的纤维形式。 纺织品提供具有与已知纺织品相当的雷达衰减性能的轻量级,并且可以形成为使得在聚合物组分中提供进一步的雷达衰减材料以提供增强的衰减效果。
