| Abstract Scope |
One of the manufacturing processes for ceramic matrix composites composed of silicon carbide fiber-reinforced silicon carbide matrix composites (SiC/SiC-CMC) is the RMI (Reactive Melt Infiltration) method, where molten silicon(Si) is impregnated into the precursor composed of SiC fiber and porous carbon(C). In order to optimize the manufacturing process by RMI method, it is essential to clarify the highly reactive Si-C interface phenomena. In the present study, dynamic contact angle measurements between Si and various types of C were performed to investigate the interfacial phenomena between Si and C. As a result, it was found that the contact angle decreased with various rate depending on the type of C substrate. Moreover, microscopic observation of the interface during and after the reaction was conducted to clarify the relationship between wettability and substrate properties such as C morphology and surface properties. |
