Abstract: Hybrid composite components, such as gas turbine engine containment assemblies, a hybrid composite component having an annular composite shell and an annular metallic shell joined with the composite shell. A containment assembly including a containment case extending along an axial direction about a longitudinal centerline of the gas turbine engine. The containment case has an inner surface and an outer surface spaced apart along a radial direction and includes a first composite shell joined with a metallic shell. The metallic shell defining a first portion of the inner surface and the first composite shell defining a second portion of the inner surface.

Abstract: A gas turbine engine composite disk includes dovetail slots between disk posts extending radially inwardly from a periphery, a hub ring of composite plies circumscribed about a centerline axis, and radial plies extending radially away from hub ring into disk posts. A segmented intermediate ring concentric with and located radially outwardly of hub ring includes intermediate ring segments having nested plies with annular bases circumscribed about centerline axis and substantially radially extending clockwise and counter-clockwise radial ply arms. An outer segmented ring may be concentric with and located radially outwardly of intermediate ring, include annular outer ring segments with circumferentially stacked composite plies disposed within intermediate ring segments between clockwise and counter-clockwise radial ply arms and radially outwardly of annular bases. An outer skin of outermost composite covering plies may extend circumferentially around composite disk. Circumferential and radial composite plies may include circumferentially and radially oriented fibers.

Abstract translation: 燃气涡轮发动机复合盘包括在从周边径向向内延伸的盘柱之间的燕尾槽，围绕中心线轴线包围的复合帘布层的轮毂圈，以及从轮毂环径向延伸到盘柱的径向帘布层。 与轮毂环径向向外同心并且位于毂环径向向外的分段中间环包括具有嵌套层的中间环段，环状基部围绕中心线轴线以及基本径向延伸的顺时针和逆时针径向层叠臂。 外部分段环可以与中间环同心并位于中间环的径向向外，包括环形外环段，其具有周向堆叠的复合层，设置在顺时针和逆时针径向层叠臂之间的中间环段内，并且环形基底的径向向外。 最外面的复合材料覆盖层的外皮可围绕复合盘周向延伸。 周向和径向复合层可以包括周向和径向取向的纤维。
