Abstract:

In order to develop flexible and broadband microwave absorbing fabric, in this paper, a new pile absorbing composite fabrics based on stereo pile fabric impregnated with acetylene carbon black and Fe-Si-Al as absorbent agent were prepared. The research results show: that the pile fabric finished by impregnation of absorbent agent has advantages of light weight, soft hand feeling and good performance of wave-absorbing; the absorption performance of pile fabric impregnated acetylene carbon black is better than that one impregnated Fe-Si-Al; When the floss length from 1to 2 cm of pile fabric impregnated acetylene carbon black, The effective band which reflection loss less than -6GHz extended to 13.5 GHz, and the absorption peaks of the reflection loss curve is less than -28 dB.
