Abstract

The carbon fibre has a good characteristic of electrical conductivity. When cut short and dispersed, it reacts as electric dipole or harmonic oscillator to radar wave. This paper blends the short carbon fibre with ethoxyline resin, and makes films by spraying the blend on prepreg which made by glass fibre and resin, then measures the EM parameters with the free-space method, and designs the low reflectivity absorbing material from 8GHz to 18GHz by matching impedance and calculating the reflectivity of multilayer films. Adjusting the kinds and quantities of matching layers can shift the absorbing frequency bands, and become better absorbing respective in X-band and Ku-band. The absorbing material samples are made by vacuumizing and heating method, and their reflectivity correspond to the designed result. The designing method and absorbing material made in this paper can be referred in engineering application.
