| ABSTRACT Stealth is the art of concealing targets from detectors. The stealth technology aims to the design and proposal of materials and techniques that can lead to the reduction of the target signature in the infrared, visible, acoustic and radar domains. In this papers, a textile barrier (cover) treated with different chemicals is used to reduce the thermal signature of a hot plate. The reduction of the infrared radiation emitted from the hot plate was measured and recorded by an infrared camera. Different types of textile have been examined and it was found that, white duck textile is the best. This textile reduces the difference between the temperature of the hot plate (100 0C) after the textile barrier and the back ground temperature (25 0C) to (15 0C) at a distance of 1 cm without any treatment. The distance between the hot plate and the textile barrier was studied in the range from 1 cm to 5 cm and it was found that, as the distance increased the temperature of the hot plate after the barrier decreased. The results show that, white duck textile without any chemical treatment reduces the thermal image of a hot plate at 100 oC by almost 83%. while its treatment by white emulsion paint reduces the thermal image of the same hot plate by 90%.The addition of titanium dixide to the paint increases the percent reduction to 91%. The other chemical additives such as talc powder,calsium carbonate, calsium sulfate, and carbon black gives lower results since these additives affect the brightness of the treated surface. However, as the areal density of these additives increases from 5.5 mg/cm2 to 11.1 mg/cm2, the results become almost the same like the treatment with paint only due to the increase in absorption. | ||||
