Abstract
Based on low temperature plasma treatment of E-glass fiber, the performance of E-glass fiber reinforced epoxy resin composites are studied. Placed E-glass fiber in the device of low temperature plasma treatment for a certain time. The chemical groups on the surface of glass fiber are observed by infrared spectrometer(FTIR), and the change of the surface element content is tested by X-ray photoelectron spectroscopy(XPS). In this paper, the influence of different treatment time on the surface energy of the material is studied, and the relationship between the surface energy and the plasma condition is established. The results showed that at different time after plasma treatment, the chemical composition of the surface of glass fiber was changed greatly and a large number of oxygen-containing groups were introduced, it improved the surface polarity of the glass fiber. It is useful to improve the wettability between glass fiber and epoxy resin. And it provides a new technology for improving the application of glass fiber reinforced epoxy resin composites.
