Effect of Plasma Treatment on Microstructure and Surface of Glass for Plastic-Based Composite

Abstract

Glass fibers and sheets were treated by the low temperature plasma process working with argon atmosphere in order to develop high performance glass fiber reinforced plastic (GFRP). In particular, surface properties, such as roughness and wetting behavior of glass fiber and sheet, were examined with plasma treatments. The surface structure of plasma-treated glass samples was observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM), and the relationship between the surface structure and the wettability was discussed. Interfacial shear strength between the plasma-treated fiber and epoxy resin was evaluated. The argon plasma treatment process improved the interfacial shear strength up to 160% of the untreated samples. The nanometer-level surface roughness of glass fiber with plasma treatment played an important role in the increase in interfacial fracture behavior. It was found that the plasma treatment process was effective for fabricating high performance GFRP.

Study on Surface Properties of Polyamide 66 Using Atmospheric Glow-Like Discharge Plasma Treatment

“…The experimental results of Nakahira et al showed that, through a short time treatment, the cold plasma could change the roughness of the organic glass surface at a relatively low power, and the superficial area of the material would increase [5]. Zhang, Shao et al [6] applied atmospheric pressure argon plasma jets, to modify the polymethyl-methacrylate.…”
