Reduction of Thermal Signature Using Fabrics with Conductive Additives
Keywords:camouflage materials, thermal signature, metal fibres, silver coated fibres, far infrared spectral range
The most effective way to reduce the thermal signature is to reduce the emissivity. The goal of our research is to create the material, which can reduce the thermal signature, and make it interflow with environment. The materials and material compositions concealing the thermal signature of the object were developed using aluminium coatings and conductive metalized fibres, i. e. yarns with stainless steel staples or coated with silver.
The analysis of the prepared samples was carried out with equipment consisting of a stand with integrated heating controller imitating the human body. The concealing properties of the samples in the far infrared (FIR) spectral range were evaluated using ThermaCAM Reporter 7.0.The thermal signature analysis of prepared samples demonstrates that respectable results could be obtained using yarns coated with silver and materials coated with aluminium, but the first one is more flexible and preferable for clothing.
