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 showed an all-polymeric 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 to impregnate glass fiber (GF) and carbon fiber (CF) to prepare conductive GFRP and CFRP laminate composites. Prepared composites were tested against simulated lightning strikes of 40 kA. Very limited visible damage was observed in both the cases.
