Assessment of the electromagnetic screening characteristics of carbon fibre composite materials
Abstract
A comprehensive study of the RF properties of a range of samples of carbon-fiber composite (CFC) materials is presented. The RF screening characteristics of samples were examined in the magnetic mode at frequencies from 150 kHz to 30 MHz and in the electric mode in the range 50-1000 MHz. The methods and techniques used in measuring the screening properties are described, and the results obtained are discussed. It is shown that CFC panels such as currently in use in aircraft construction are inherently capable of providing high attenuation at frequencies in the VHF band and above. In the HF band the attenuation of magnetic fields will fall approximately directly with decreasing frequency and is unlikely to exceed 20 dB at frequencies below 1 MHz.
