Abstract: Aspects of the invention relate to a construction system and method for components in high temperature environments, such as the hot gas path components of a turbine engine. Such a component can include a skeleton and a coating. The skeleton can be formed by a plurality of interconnected frame members, which can give the component its general shape. The frame members can be made of ceramic matrix composite. A coating can be provided around at least a portion of the skeleton. Preferably, the coating is a refractory material, such as refractory ceramic. Examples of turbine engine components that can be constructed according to aspects of the invention are airfoils with or without platforms, blade rings, combustor tiles and heat shields. A component according to aspects of the invention can be made using low cost fabrication and construction methods.

Abstract: A ceramic article having improved interlaminar strength and a method of forming the article. The article may be a ceramic matrix composite article. The methods of forming the articles increase the interlaminar strength of the article by forming indentations in the article during processing. The indentations may be tabs that are formed such that they provide one or more beneficial features for ceramic articles, such as CMC articles and hybrid structures. The tabs may be any of a variety of shapes, orientations, spacings, and combinations. In an alternative embodiment, the indentations are formed by pulling one or more fibers from one side of the ceramic layer to the other side. The articles have increased surface area, which helps to increase the bonding strength between the ceramic layer and any thermal barrier coating layer and/or ceramic core in the ceramic article.

Abstract: A joining method for assembling components with complex shapes from CMC elements of simpler shapes. A first CMC element (30) is fabricated and fired to a selected first cured state. A second CMC element (36) is fabricated and left in a green state, or is fired to a second partially cured state that is less complete than that of the first cured state. The two CMC elements (30, 36) are joined in a mating interface that captures an inner joining portion (38) of the second element (36) within a surrounding outer joining portion (32) of the first element (30). The assembled elements (30, 36) are then fired together, resulting in differential shrinkage that compresses the outer joining portion (32) onto the inner joining portion (38), providing a tightly pre-stressed joint. Optionally, a refractory adhesive (42) may be used in the joint. Shrinkage of the outer joining portion (32) avoids shrinkage cracks in the adhesive (42).

Abstract translation: 用于从简单形状的CMC元件组装具有复杂形状的部件的接合方法。 制造第一CMC元件（30）并将其烧制至所选择的第一固化状态。 制造第二CMC元件（36）并保持在绿色状态，或者被烧制到比第一固化状态不完全的第二部分固化状态。 两个CMC元件（30,36）连接在配合接口中，该接合接口在第一元件（30）的周围的外部接合部分（32）内捕获第二元件（36）的内部接合部分（38）。 然后将组装好的元件（30,36）烧结在一起，导致不均匀的收缩，将外部接合部分（32）压缩到内部接合部分（38）上，从而提供紧密的预应力接头。 可选地，可以在接头中使用耐火粘合剂（42）。 外接合部分（32）的收缩避免了粘合剂（42）中的收缩裂纹。
