A method of making fabrics and coatings in a camouflage pattern with a printed camouflage pattern ink layer covered by a temperature activated color changing ink layer or layers printed in a camouflage pattern, which matches the pattern in the underlying printed camouflage fabric ink layer. The temperature activated color changing ink layer changes color state with a change of temperature to another color state or a clear state, which reveals the color state of the underlying printed camouflage fabric layer. The temperatures at which the temperature activated color changing ink changes color state occurs at a pre-determined temperature so that the camouflage pattern reveal the color states and the characteristics of the foliage of the season to which the temperature corresponds.

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.

A multi-axial geogrid possesses a series of interconnected strands or ribs that are arranged along at least two different axes within the plane of the structure. The strands or ribs have an aspect ratio, defined as the ratio of the thickness to width, of greater than 1.0, thickness being the direction normal to the plane of the structure. The geogrid can be manufactured by modifying the process parameters in order to create high aspect ratio ribs, using any of the various known methods for producing geogrids. A reinforced civil engineering structure, and method therefor, is formed by embedding in soil one or more horizontal layers of geogrid having high aspect ratio ribs. The reinforced structure shows improved rutting performance when subjected to vehicular traffic.
