(TU Delft Structural Integrity & Composites) Villegas, I.F. (TU Delft Structural Integrity & Composites) Bersee, H.E.N. (TU Delft Structural Integrity & Composites) Date 2016 Abstract The process-induced voids during resistance welding of glass fabric-reinforced polyetherimide was investigated. The mechanisms of void formation in adherends, in particular, the residual volatile-induced voids and the fibre de-compaction-induced voids, were analysed. Due to the non-uniform temperature and stress distributions in the joints during welding, a non-uniform void distribution was observed in the joints with more voids generated in the middle of the joints than at the edges. Welding temperature and pressure were shown to have a large influence on void formation. Increasing of welding pressure was shown to effectively reduce the voids, while the residual moisture-induced voids were found more difficult to be eliminated than the fibre de-compaction-induced voids Subject Thermoplasticcompositesresistance weldingvoidspolyetherimide To reference this document use: http://resolver.tudelft.nl/uuid:f4ba276e-f8a7-40cf-9ba5-1b78d7ab637d DOI https://doi.org/10.1177/0892705716662514 Embargo date 2018-01-01 ISSN 0892-7057 Source Journal of Thermoplastic Composite Materials, 30 (12), 1654-1674 Bibliographical note pr Part of collection Institutional Repository Document type journal article Rights © 2016 H.
