Abstract
Because of its inertness and poor impregnation of resin, it is essential to enhance the interfacial performances of PET/epoxy composites by improving its polarity. After PET fiber is treated by cold plasma technology, ESCA is used to analyze the elemental composition and the type of functional groups of the surface of PET, and SEM is used to observe the interlaminar shear fracture. The impregnation of the PET fiber and the interfacial performances of PET/epoxy composites are studied. The results show that after cold plasma treatment, the increase of oxygen and nitrogen functional groups in the surface improves the surface impregnation of PET fiber and the interfacial shear strength (IFSS) property of PET/epoxy composites.
