Development Of Infrared Jamming Material And Attenuation Performance

The preparation and capacity of the smokescreen materials against infrared wave were studied in the dissertation. Firstly, the new methods to measure the anti-infrared ability of graphite and carbon fibre with the dual-waveband infrared radiation instrument were be found. The short carbon fibre was specially dispersed to KBr and planished tablet, and the result is consistent with the Lamb-Beer rule. Secondly, the technology of electroless copper plating on graphite surface was optimized. By reason of the Cu2O consist in the copperized surface, it is showed that the conductivity and anti-infrared capacity of graphite was effected. Thirdly, the conductive mica powder was first to applied in the smokescreen field. The technology of electroless nickel plating on the mica powder was optimized. The electroless nickel plating mica powder has well conductivity and disperse. It is showed the anti-infrared capacity of the electroless nickel plating mica powder is more than the mica powder's.
