ABSTRACT
The reduction of radar signature for textile fabric by treating with carbon black
powder dissolved in shellac solution (shellac dissolved in ethanol) is investigated. In
this study, carbon black was added with known concentration in shellac solution and
mixed until solution formula was homogenous. Also, the textile fabrics were chosen
from the commercially available ones with known specifications and
characterizations. All of them were obtained before dyeing and without any further
treatment and they were prepared with known dimensions. Another different
polymeric compound was used with carbon black which was commercial epoxy resin.
The prepared textile fabric was treated with the solution of carbon black and
dissolved shellac by impregnation of the textile sample or by coating in case of using
carbon black mixed with epoxy resin. After treatment of textile fabric with the
chemical solution containing carbon black, the obtained textile sample was tested by
microwave reflectometer to measure the reduction in reflected radar power and so
the reduction of radar signature. The results of these measurements were recorded.
