Abstract
A method for joining a ceramic matrix composite (CMC) component includes placing a plurality of joining plies onto a specified area such that a respective fiber direction of each of the plurality of joining plies is off-plane to a fiber direction of one or more composite plies of the specified area. The respective fiber direction of each of the plurality of joining plies differs from the respective fiber direction of each adjacent one of the plurality of joining plies.

A method for joining a ceramic matrix composite (CMC) component, the method comprising:
- placing a plurality of joining plies into a repair area, the repair area defining an interface between a first part of the CMC component and a second part of the CMC component, the first part comprising a first plurality of composite plies stacked in a first stacking direction adjacent the interface, and the second part comprising a second plurality of composite plies stacked in a second stacking direction adjacent the interface, wherein the first stacking direction and the second stacking direction are different, each of the plurality of joining plies being stacked in a third stacking direction at the interface that is different from the first and second stacking directions planes;
- and
- forming an integral component by bonding the plurality of joining plies to the repair area.
A method for joining a ceramic matrix composite (CMC) component, the method comprising:
- placing a ply stack defined by a plurality of joining plies into a specified area defining an interface between a first part of the CMC component and a second part of the CMC component, wherein the first part comprises a first plurality of composite plies stacked in a first stacking direction adjacent the interface, and the second part comprising a second plurality of composite plies stacked in a second stacking direction adjacent the interface, wherein the first stacking direction and the second stacking direction are different, and wherein each of the plurality of joining plies is stacked in a third stacking direction different from the first and second stacking directions.
