Fernandez Villegas, I. Bersee, H.E.N. Faculty Aerospace Engineering Department Aerospace Structures & Materials Date 2015-07-19 Abstract Void formation in resistance welding of woven fabric reinforced thermoplastic composites was investigated. Void contents were measured using optical microscopy and digital image process. Un-even void distributions were observed in the joints, and more voids were found in the middle of the joints than the edges. A higher welding pressure was shown to help reduce the void generation. The mechanisms of void formation, in particular fibre de-compaction induced voids and residual moisture induced voids, were analysed. The model estimations were correlated with the experimental results.
