PERFORATED CERAMIC MATRIX COMPOSITE PLY, CERAMIC MATRIX COMPOSITE ARTICLE, AND METHOD FOR FORMING CERAMIC MATRIX COMPOSITE ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a perforated ceramic matrix composite ply, a composite article, and a method for forming the composite article.SOLUTION: An article (100) includes at least one shell ply (102) forming an exterior wall (104) having a first portion (108) and a second portion (110) and defining a plenum (106). An annular brace (112) formed of at least one structural support ply (124) includes: a first curved portion (116) extending from a first integral portion (114), which is integral with the first portion of the exterior wall and is part of the first portion, and curving across the article plenum to the second portion of the exterior wall; a second curved portion (120) extending from a second integral portion (118), which is integral with the second portion of the exterior wall and is part of the second portion, and curving across the article plenum to the first curved portion; and an overlap portion (122) in which the first curved portion and the second curved portion (120) are integral.SELECTED DRAWING: Figure 1
