Abstract

The deposition of coatings on the surface of carbon fiber will be helpful to their applications. However, they are unsuitable to be deposited because of their low surface free energies, poor wettability and poor adhesions. The objective of this work is to modify carbon fibers by different methods of plasma grafting polymerization. The chemical and physical changes induced by the treatments on carbon fibers surface can be examined by using contact angle measurements and X-ray photoelectron spectroscopy (XPS). The interfacial adhesion of CF/EP composites is analyzed by a single ber composite (SFC) for filament fragmentation test. The contact angles of the plasma-treated samples are visibly reduced compared to the untreated samples. The results of XPS reveal that the carbon fibers modified with the plasma grafting methods show a significant increase in oxygen-containing groups, such as C–O,C=O and O–C=O. The results of SFC tests show that the treated carbon fibers composites could possess excellent interfacial properties with mixed resins. These results demonstrate that the surfaces of the carbon fibers samples are more active, more hydrophilic and rougher after appropriate plasma grafting disposal.
