Abstract SiC foams sandwiched between two Ceramic Matrix Composite (CMC) skins are of interest for several high temperature applications ranging from aeronautics to energy production. In this paper, SiC foams were joined to C/SiC composites by the “Mo-wrap” method to obtain sandwich structures. The Mo-wrap method is a recently developed joining technique: it consists of wrapping Si foils inside a Mo wrap in order to prevent molten silicon leaking from the joined area and infiltrating SiC foam and C/SiC during the joining process. Compression and thermal shock resistance tests were performed on the C/SiC – SiC foam – C/SiC sandwich obtaining sound results.

Mo-wrap连接获得的SiC泡沫夹层结构

摘要 夹在两个陶瓷基复合材料 (CMC) 表皮之间的 SiC 泡沫对从航空到能源生产的几种高温应用很感兴趣。在本文中，通过“Mo-wrap”方法将 SiC 泡沫与 C/SiC 复合材料连接以获得夹层结构。Mo-wrap 方法是最近开发的连接技术：它包括将 Si 箔包裹在 Mo 包裹内，以防止熔融硅从连接区域泄漏并在连接过程中渗入 SiC 泡沫和 C/SiC。对 C/SiC – SiC 泡沫 – C/SiC 夹层进行了抗压和抗热震测试，获得了良好的结果。
