The penetration and carrying ability of supercritical carbon dioxide were used to eliminate fibers’ agent and carry coupling agent (KH-560) into fiber to modify the hollow/solid hybrid quartz fibrics. The surface energy and interfacial tension of modified fiber and the adsorption with resin were measured. The surface morphology of fibers was observed. The results showed that most of the fibers’ agent was removed in the Heat treatment+Solvent bathing+Supercritical carbon dioxide treatment process. The surface energy of fibers was increased, and this indicates that the hybrid quartz fibrics could be impregnated much better by modified cyanate resin. All indicated that the treatment process can improve the mechanical and dielectric properties of composite materials.
