Presentation transcript:

Resistance welding of thermoplastic composites Background Thermosetting and thermoplastic polymers are two kinds of matrix for fibre reinforced polymer (FRP) composites. Compared with thermosetting composites (TSC), thermoplastic composites (TPC) are more environmentally friendly for both manufacturing and recycling processes. Compared with mechanical joining and adhesive bonding techniques, resistance welding has been regarded as a more suitable joining techniques for TPCs, and it has already been applied in the aircraft industry for secondary structures, i.e. the fixed leading edges of A380. In order to apply TPCs for the primary structural components such as fuselage and wings, key technologies related to the manufacturing of TPCs are being developed in the frame of TAPAS project. Therefore, in order to utilize resistance welding for primary TPCs structure, higher level knowledge of the welding mechanisms should be known. Publications -Shi H, Villegas IF, Bersee HEN.

Schematic drawing of resistance welding setup Source: Fokker Aerostructures, the Netherlands Progress 1: Welding process model Transient heat transfer models are developed for both static resistance welding and continuous resistance welding, based on which welding mechanisms such as consolidation, crystallization and squeezing flow are also looked into. Progress 2: Welds quality characterization In order to assess the quality of the resistance welded structures, reliable testing method should be selected. Therefore, various mechanical testing methods are employed and compared. Progress 3: Process induced voids An investigation on the process induced voids/porosities, i.e. residual volatile induced voids and fibre de-compaction induced voids, is performed. Progress 4: Welds quality optimization In order to improve the mechanical performance of the welds, the effect of heating time, heating element, fibre orientation and fibre-matrix adhesion on the welds quality is studied. Progress 5: Process control A welding quality control strategy for resistance welding process is proposed by detecting and utilizing the weld- thickness evolution.
