A method for patching a damaged polymeric erosion coating () on a gas turbine engine component. The method comprises removing a portion of the coating around a damage site () and applying a pre-formed coating patch ().

Turbine engine repair methods

A method includes positioning a layer of adhesive between a first structural component and a second structural component, positioning a first evaluation film between the first structural component and the layer of adhesive, curing the adhesive at least partially, separating the first structural component and the first evaluation film by a relative movement therebetween, and inspecting bond line quality of the adhesive.

Method and assembly for validating bond line

A mandrel comprising a rigid inner core and an elastomeric outer layer that at least partially surrounds the rigid inner core, wherein the elastomeric outer layer is adapted to expand during a molding process to seal a cavity to prevent incursion of material injected during the molding process.

Hybrid mandrels

A process for manufacturing a composite structure includes the steps of disposing a removable adhesive material in contact with a first surface of a reusable composite structure; disposing a first surface of an expendable composite structure in contact with the removable adhesive material to form a composite structure assembly; and curing the composite structure assembly.
