Structure repair with polymer matrix composites

摘要

An assembly is provided including a structural component having a flange-like member. A partially cured polymer matrix composite patch is wrapped around a perimeter of the flange-like member. The patch includes a plurality of layers, each layer having a plurality of fibers arranged therein. The layers of the polymer matrix composite patch are cured after being wrapped around the flange-like member of the structural component.

主权项

1. A method of forming a polymer matrix patch about a load-bearing, metallic structural component, comprising:
wrapping a plurality of layers around the surface of a flange-like member of the load-bearing, metallic structural component in-situ, such that the patch extends parallel to an axis of the flange-like member and wraps equidistantly, over two opposing sides of the load-bearing metallic structural component such that a first end and a second, opposite end of each the plurality of layers is arranged within a same plane on opposing sides of the structural component, each layer having a plurality of fibers arranged therein; and curing the plurality of layers.
