Improved mechanical properties of resistance welded joints of thermoplastic composites by versatile graphene oxide

An approach of adding graphene oxide (GO) nanosheets to enhance the joints for resistance welding glass fabric reinforced polyetherimide (GF/PEI) laminates was proposed in this study. The GO nanosheets were introduced and dispersed uniformly into the heating element (HE) of carbon fiber (CF) bundles coated PEI and the welding adhesives of PEI films in the different weight ratios. The GO nanosheets were prepared firstly by the modified Hummers...
