The purpose of the present work was to investigate the effects of oxygen-plasma treatment on tensile deformation of nano-SiO2 sol-gel coating T-300 carbon fiber (HONS3C) were studied and a new concept for the nano-structural interphase between fiber surface and nano-coating provided in the paper. The tensile test results showed that besides the enhanced ductility of T-300 carbon fibers by nano-SiO2 sol-gel coating the T-300 carbon fibers treated by oxygen-plasma, the activation volumes of T-300 carbon fibers untreated and treated with oxygen-plasma ranging from 681.9628 to 32342(nm)3 by following Eyring’s equation were important descriptors for the properties of the nano-structural interphase between fiber surface and nano-coating, From the results of SEM and FTIR, it was observed that the uniform dispersion of the nano-SiO2 coating of the T-300 carbon fibers treated by oxygen-plasma not only formed a protective layer to cover the fibers, but also introduced the activated functional groups on the fiber surfaces.
