Ceramic composite tubular structure

HENSON GRANT MYRON / DESCELLE DOUGLAS GLENN

A ceramic composite tubular structure includes a tubular monolithic ceramic preform produced using an additive manufacturing process. The monolithic ceramic preform includes a first end, a second end, an inner surface, and an outer surface. The monolithic ceramic preform includes one or more apertures formed between the inner surface and the outer surface, wherein at least one of the one or more apertures is open to at least one of the first end or the second end. The inner panel is formed from a first number of ceramic matrix composite layers on an inner surface of the monolithic ceramic preform. An outer panel is formed from a second number of ceramic matrix composite layers on an outer surface of the monolithic ceramic preform.

一种陶瓷复合管状结构，包括使用增材制造工艺产生的管状的单体陶瓷预成型件。该单体陶瓷预成型件包括第一端、第二端、内表面和外表面。该单体陶瓷预成型件包括在内表面和外表面之间形成的一个或多个孔，其中该一个或多个孔中的至少一个孔向第一端或第二端中的至少一个开放。内面板由第一数量的陶瓷基质复合层形成在单体陶瓷预成型件的内表面上。外面板由第二数量的陶瓷基质复合层形成在单体陶瓷预成型件的外表面上。
