A system is provided for monitoring a relative displacement of a pair of end-winding components. The system includes a structure mounted to the end-winding components at an angle with respect to the end-winding components for monitoring the relative displacement. The system further includes an optical fiber with a first portion including a fiber Bragg grating mounted to a surface of the structure to experience a strain resulting from a strain of the structure due to the relative displacement. The optical fiber includes a second portion internally routed through in the structure to the first portion mounted to the surface. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the end-winding components.

An apparatus and methods for manufacturing a flanged component from a composite lay-up are provided. The apparatus includes a support structure coupled to the composite lay-up and a mold ring coupled to the support structure. The mold ring includes a ring guide surface and a radial contact surface that is configured to couple to the composite lay-up. The apparatus further includes a mold plate coupled to the mold ring. The mold plate includes a recessed surface and a plate guide surface, where the recessed surface is configured to couple to the composite lay-up and the plate guide surface is configured to couple to the ring guide surface. The apparatus also includes an autoclave that applies pressure to the mold ring and the mold plate to move the plate guide surface along the ring guide surface to apply pressure to the composite lay-up.

A method of manufacturing a flanged composite component is provided. The method includes coupling a composite structure to s first composite material. The method includes coupling a second composite material to the composite structure and placing a first expansion device within the composite structure. A forming element is coupled to at least one of the first composite material, the composite structure, and the second composite material against the mold. The method includes coupling a pressure element to the forming element to define a space among the mold, the forming element, and the pressure element. The method includes expanding the first expansion device to impart a force to the second composite material to move the second composite material away from the composite structure and into the space to facilitate forming a first flange.
