Abstract
Official abstract text for this publication.
A method for joining a first CMC part ( 30 ) having an outer joining portion ( 32 ), and a second CMC part ( 36 ) having an inner joining portion ( 38 ). The second CMC part ( 36 ) is heat-cured to a stage of shrinkage more complete than that of the first CMC part ( 30 ) prior to joining. The two CMC parts ( 30, 36 ) are joined in a mating interface that captures the inner joining portion ( 38 ) within the outer joining portion ( 32 ). The assembled parts ( 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 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of forming a joint in a ceramic component, the method comprising: adjoining a first surface of a first ceramic member to a second surface of a second ceramic member; disposing a ceramic matrix composite compression ring about the adjoined surfaces, the first and second ceramic members being cured to a stage of shrinkage greater than a stage of shrinkage of the compression ring; co-firing the first ceramic member, the second ceramic member…
