A method of forming a ceramic matrix composite gas turbine engine component includes the steps of: providing a plurality of green sub-elements of the component, each sub-element containing stacked plys of continuous fibre reinforcement embedded in a green ceramic matrix; assembling the sub-elements into an arrangement in which each sub-element contacts at least one other sub-element, the arrangement corresponding in shape to the final component; and sintering the assembled sub-elements to fuse the ceramic matrix within each sub-element and between contacting sub-elements, thereby forming the component as a ceramic matrix composite unitary body. An alternative method includes ceramic cement being provided at the contact interfaces between the sub-elements and the assembled sub-elements to fuse the ceramic cement, thereby forming the component as a ceramic matrix composite unitary body. |
