The Effect of Surface Treatment on the Resistance Welding Technology for Carbon Fiber/Epoxy Resin Composites
In this research, a high-efficiency joining technique of resistance welding is proposed to achieve high-quality joining of carbon fiber/epoxy (CF/Epoxy) composites. The effects of mechanical sanding and dielectric barrier discharge (DBD) plasma surface modification were investigated on joint properties. Through morphology observation, wettability research, and surface chemical element analysis, it was found that both methods effectively improved joint performance. Mechanical sanding increased surface roughness, facilitating mechanical interlocking between composite layers. DBD plasma treatment enhanced surface wettability, promoting better adhesion between the materials. Notably, the failure mode of the welded joint transformed from interface failures to interlayer failures, indicating improved joint integrity and strength. The combined treatment method, using both mechanical sanding and plasma treatment, yielded the highest single lap shear strength (LSS) of 25.78 MPa, which was an impressive 141.2% higher than the untreated sample.
期刊介绍：
Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes.
Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
