| Abstract: | The Li2O/SiO2 coating on the carbon fiber was prepared using sol-gel method.The microstructure of carbon fibers with and without Li2O/SiO2 coating has been studied.Interfacial layers with a multi-layer morphology originated from the diffusion of lithium from the β-spodumene matrix to the surface of the carbon fiber,which led to the formation of graphite intercalation compounds.The mechanical properties of Cf/LAS were enhanced due to the textured interfacial microstructure of graphite intercalation compounds. |
