Research on the strength enhancement of resistance welding of carbon fiber/epoxy composites by atmospheric plasma surface treatment
Source abstract
Abstract
In order to improve the lap shear strength (LSS) of carbon fiber/epoxy composite resistance welding joint, this study used atmospheric plasma to treat the CF/EP surface to improve its physical and chemical properties and enhance its resistance welding strength with thermoplastic resin (PA6). This study investigated the effects of atmospheric plasma treatment power (800 W, 900 W, 1000 W) and treatment time (30 s, 35 s, 40 s) on the LSS of CF/EP resistance welding joint. The results show that the enhancement mechanism of CF/EP resistance welding joint varies with changes in treatment power and treatment time. Extending the treatment time at low treatment power can improve the LSS value of CF/EP resistance welding joint to a limited extent, while extending the treatment time at high treatment power weakens the enhancement effect of atmospheric plasma treatment on the LSS value of CF/EP resistance welding joint. The LSS value of CF/EP resistance welding joint can only be maximized when atmospheric plasma treatment is performed at the appropriate treatment power and treatment time. The study results show that the optimal atmospheric plasma treatment parameter is 900W/35s (i.e. atmospheric plasma treatment of CF/EP at a treatment power of 900W for 35s). When the CF/EP surface is treated with the atmospheric plasma under the optimal treatment parameter, the LSS value of the CF/EP resistance welding joints can reach 21.35 ± 1.17 MPa, which is an increase of approximately 161% compared to the untreated CF/EP welding joints. By observing the surface morphology of CF/EP after atmospheric plasma treatment and analyzing the wettability and chemical composition changes of the CF/EP surface, it can be seen that atmospheric plasma treatment not only effectively improves the roughness of the CF/EP surface, but also generates a variety of oxygen-containing polar groups on the CF/EP surface, improving the wettability of the CF/EP surface. This improves the interfacial bonding strength between the CF/EP surface and the thermoplastic resin, changes the failure mode of the CF/EP resistance welding joint, and significantly improves the LSS value of the CF/EP resistance welding joint.
