Surface modification of carbon/epoxy prepreg using oxygen plasma and its effect on the delamination resistance behavior of carbon/epoxy composites

Surface adsorption and wetting properties of amorphous diamond-like carbon thin films for biomedical applications

“…The stress in the DLC films formed by unbalanced sputtering and cathodic arc was compressive and the films were dense. Kim et al investigated the effect of oxygen plasma on the surface properties of carbon using the X-ray photoelectron spectroscopy (XPS) technique [18]. Their results showed that the hydrophilic carbonyl C_O group was formed by the oxygen plasma.…”

Air dielectric barrier discharges plasma surface treatment of three-dimensional braided carbon fiber reinforced epoxy composites

“…Meyer [5] carried out surface etching of three dimensional shaped parts of carbon fiber reinforced epoxy and PEEK composites by plasma etching with an O 2 and C 2 F 6 mixture. Kim et al [6,12] investigated the surface of carbon/epoxy layers of prepregs by examining the strength of single lap composite adhesive joint after argon plasma or oxygen plasma treatment. Kyong [13] inspected the peel strength and the shear strength of aluminum/CFRP composites in which the surface of the aluminum was treated using DC plasma and the surface of the CFRP was treated by Ar + ion assisted reaction method under oxygen environment.…”

Effect of oxygen plasma treatment on the bonding strength of CFRP/aluminum foam composite

“…The ratios of the area of the C C peak, C O peak, C O and O C O peaks were 50.7%, 30.1%, 9.4%, and 7.4%, respectively [16]. Consequently, the oxygen plasma treatment changed the chemical components on the CFRP surface and the newly formed functional groups improved the surface polarity and its hydrophilicity [16][17]. …”
