膜沸騰法による炭素繊維強化／炭化珪素複合材料の開発

Film boiling is one of the heat transfer phenomena in which a liquid phase boils and the vapor film covers a solid phase to maintain steady heat transfer when the heat flux from the solid phase to the liquid phase is large. When a carbon fiber is used as a solid phase and an organic solvent is used as a liquid phase and a solid-liquid interface is heated to a high temperature, film boiling occurs, the vapor phase derived from the organic solvent is formed in the carbon fiber, and pyrolytic carbon can be rapidly deposited onto the carbon fiber from the vapor phase. Characteristics of this formation technology include shortening process time, densification of generated carbon, and remarkable graphitization property. In this study, the authors examined a manufacturing method of carbon fiber reinforced/silicon carbide composite material using this film boiling phenomenon.
