Abstract

A carbon fibre or aramid fibre fabric in a matrix of thermoset plastic is coated first with a thin layer of nickel, then with a highly conductive second layer, and on the outside once more with nickel. If the metals are deposited under wet-chemical currentless conditions, the flexible fabric will be electrically highly conductive. The composite material is particularly suitable for lightning and NEMP protection.
