【Abstract】 Nanometer modified films was formed on the surface of the fiber by vacuum plasma. The resin matrix composite was reinforced by the modified fibers. The electro-magnetic property and wave-absorbing property of the composite were tested. The results show that the wave-absorbing property of the fiber reinforced composite can be effectively improved by nano-surface modification. The reflectivity of the composite is -(2.6～6.1)dB in 8～18 GHz. The wave-absorbing curve has such character as wide wave-absorbing frequency. The mass increment of the material is almost zero.更多还原
