Carbon fiber structural radar absorbing materialsand preparation of radar absorbing carbon fibers

Carbon fiber structural radar absorbing materials ( SRAM ) are multifunctional composites with high strength, modules and reducing radar cross section ( RCS ), which are increasingly receiving recognition as practical structural functional composites with good prospect. Carbon fiber structural radar absorbing materials have been widely used in stealth technology with good mechanical and stealth prorerty. In this paper, carbon figer SRAM are reviewed from its utilization in stealth aircraft, styles and structure design. The future research tendency regarding the carbon fiber SRAM is presented. The preparation methods of radar absorbing carbon fiber have been discussed. The radar absorbing carbon fiber can be prepared by decreasing the heat-treatent temperature of carbon fiber, changing the cross section shape and size of carbon fiber, modifying the carbon fiber surfcae and doping other elements into carbon fiber.
