METHOD OF PRODUCING AN INTERNAL CAVITY IN A CERAMIC MATRIX COMPOSITE AND MANDREL THEREFOR
A process for producing an internal cavity in a CMC article and mandrels used therewith. The process entails incorporating a mandrel made of a material that is substantially absorbed during thermal treatment of a preform to form the CMC article. The mandrel material is preferably reactive with one or more constituents of the CMC preform during the thermal treatment. The material is preferably silicon or a silicon alloy.
本发明涉及一种在陶瓷基质复合材料中产生内腔室的方法。用于在CMC制品中产生内腔室的过程及与其一起使用的心轴。该过程需要并入由可熔材料制成的心轴，该可熔材料在CMC预成型件的热处理期间被熔化和排出，以形成CMC制品。心轴材料优选为在热处理期间不润湿CMC预成型件的任何组分并且与CMC预成型件的任何组分不反应。心轴优选为锡或锡合金。
