Abstract
Geometrically incised fabrics that control reflectance and transmission in the visible, thermal, nIR, SWIR, and microwave/millimeter bands of the electromagnetic spectrum are provided. The incised fabrics include incised flaps that move about a hinged attachment portion into open and closed configurations. The incised flaps may be oriented in patterns containing overlapping, inverted incised flaps, overlapping inverted and non-inverted incised flaps, or in block patterns of incised flaps. Selective transmission of electromagnetic waves can be modulated by the geometry of the incised flaps and the amount of tension applied to the incised fabric. The incised fabric includes a composite material including an asymmetric ePTFE laminate, a metalized layer, an ePTFE membrane layer, and a textile. A second ePTFE asymmetric laminate and a metal layer may be attached to the composite material to form a reversible composite. Incised fabrics may be used to form selective, multispectral reflective covers and garments.
