Abstract
Most common lightning strike protection (LSP) technology consists of expended metal foils/films on top of composite structures. This technology possesses disadvantages such as increased weight, galvanic corrosion, expensive integration and repair process. In the present study, authors introduce a novel, all-polymeric, easy to apply and easy to repair LSP technology and confirmed its effectiveness against lightning strike. Polyaniline is an intrinsic conductive polymers, which can be rendered conductive by doping with a strong acid. Dodecylebenzesulfonic acid is used as dopant for PANI in current work. Authors, prepared a thermosetting resin system, where, DBSA doped PANI complex (semi-doped) was mixed with divinylbenzene (DVB). This conductive resin system was used in two ways, firstly to impregnate GF fabrics to prepare conductive GFRP laminate composite and secondly as a thin conductive layer (PANI-film) on the top of epoxy based GFRP laminate. Prepared composites were tested against simulated lightning strikes of 40 kA & 100 kA. Almost no visible damage was observed in both the cases.
