Processing and optimisation of a conductive poly(epoxy) : silver submicronic wires coating for lightning strike protection of aircraft structural composite parts
Abstract
This work deals with the processing and the study of an extrinsic conductive polymer coating for the lightning strike protection of the aircraft carbon fibre reinforced polymer (CFRP) structural parts. The coating consist in a low viscosity bi component high performance poly(epoxy) matrix and silver submicronic wires with a high aspect ratio (AgNWs) obtained by a polyol process. The kinetic parameters, the physical structure and the molecular mobility of the matrix had been investigated as a function of the filler content. The surface and bulk conductivities had been measured as a function of filler content. It exhibits a percolation threshold below 1% in volume. The conduction mechanisms had been studied following an uncommon method of current density measurement as a function of the AgNWs content and the temperature. The critical electrical behaviour of each sample had been investigated through the current density method. It has permitted to understand the phenomenon responsible for the composite's degradation. Finally, lightning strike tests on representative configurations had been carried out. The ultrasonic inspections have highlighted the efficiency of the poly(epoxy)/AgNWs coating to avoid the structural delamination of the CFRP.
