“…17 Both specimen types presented similar load-displacement curves. 13 The CF/PEI and GF/ PEI specimens exhibited a linear behaviour up to the maximum load, which was followed by sudden failure, while the CF/PEEK and CF/PEKK specimens exhibited a linear (elastic) behaviour initially, followed by non-linear response to failure ( Figure 5). Very similar LSS was also obtained in both configurations with less than 5% difference between SLS and DLS specimens for every material being tested (Figure 4).…”

“…The selected parameters are based on previous studies, demonstrating that those temperatures and pressures lead to good weld quality. 6,11,13 In particular, it was shown by Talbot et al 11 that the parameters that were used led to a complete weld avoiding polymer degradation. Once the first weld was done, the specimen was flipped over and was resistance welded again with another laminate (Figure 2).…”

“…The stainless steel mesh heating element size (wire diameter and open gap width) was optimized for better mechanical performance. 12,13 Failure modes of SLS and typical aerospace skin/stringer joints were also reported. 8,9 The effect of fatigue loading on resistance-welded joints has not been studied extensively.…”

An experimental investigation of resistance welding of thermoplastic composite double lap shear (DLS) joints is presented. DLS specimens consisting of unidirectional carbon fibre/ polyetheretherketone (CF/PEEK), carbon fibre/polyetherketoneketone (CF/PEKK), carbon fibre/polyetherimide (CF/PEI) and 8-harness satin weave fabric glass fibre/polyetherimide (GF/PEI) composites were resistance welded using a stainless steel mesh heating element. The welded specimens were tested under static and fatigue loadings, and the quality of the welds was examined using optical and scanning electron microscopy. Weld strengths of 53, 49, 45 and 34 MPa were obtained for CF/PEEK, CF/PEKK, CF/PEI and GF/ PEI DLS joints, respectively. Indefinite fatigue lives were obtained between 20 and 30% of the ultimate static failure loads of the joints. Performances of the resistance-welded DLS and single lap shear (SLS) joints were compared. It was shown that the effect of joint geometry, that is, DLS versus SLS, on the mechanical performance of the resistancewelded joints is minimal, indicating a good resistance of welded joints to peel stresses.

“…In literatures, many hypotheses have been proposed aiming to explain void generation during welding of thermoplastic composites. 5,8,10,12,[21][22][23][24] Voids were observed in the weld line of dual-polymer welded graphitepolyarylsulfone/polysulfone (PAS/PS) composites owing to trapped volatiles and overheating at the weld interface. 8 Xiao et al 8 developed a thermal buckling model to analyze voids and de-consolidation induced during induction heating of carbon fibre reinforced polyetheretherketone (CF/PEEK), and indicated that thermal stress induced in the non-uniform temperature fields of the parts was the cause of voids.…”

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 analyzed. 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.

The surface modification of stainless-steel (SS) mesh was carried out by chemical etching for different time, and then, the etched SS meshes were used as the interlayer heating element for resistance welding of glass fabric-reinforced polyetherimide (GF/PEI) composite laminates. The hydrophobicity and tensile strength of the etched and untreated SS wires and interfacial shear strength (IFSS) between SS wire and PEI resin were investigated by dynamic contact angle (DCA) analyzer and single fiber pull-out test to evaluate the influence of the degree of chemical etching on the bonding strength of PEI resin and SS surface. Tensile lap-shear strength (LSS) and scanning electron microscope (SEM) analysis were performed to investigate the welding interface strength and fracture morphologies of the resistance-welded joint of the GF/PEI laminates. The hydrophobicity and tensile strength of SS wires were increased and decreased respectively with etching time (t e ). The IFSS of SS wire/PEI resin showed an improvement with t e . The LSS was increased first and then decreased with t e , and the optimal t e was 30 min when LSS reached the maximum. Fracture analysis showed the main failure mode of the welded joints was the interlayer debonding when welding time (t w ) was insufficient. With the extension of t w , the failure mode gradually switched into the intralayer tearing of the SS implant.
