Embodiment Construction

[0056] The present disclosure relates to repairing composite components, such as stringers to the structure of aircraft and other mobile platforms (eg, vehicles). For the purposes of this disclosure, the term "composite" is intended to encompass fiber-reinforced composites (e.g., polymers) and advanced composites, also known as advanced polymer matrix High-strength fibers bound together by a matrix material. For example, such composite materials may include fiber reinforcements, such as carbon, aramid, and / or glass fibers embedded in a thermoset or thermoplastic matrix material. It should be understood that aspects of the present disclosure may be applicable to the repair of stringers or other components made of other non-metallic materials.

[0057] In various aspects, the present disclosure describes methods and apparatus for repairing composite stringers that are part of the structure of a mobile platform. In some embodiments, the repair methods disclosed herein utilize a...

Abstract

Methods and composite repair caps (26) for repairing composite stringers (12) of structures (10) of mobile platforms are disclosed. In one exemplary embodiment, a stringer repair method includes overlaying a pre-cured composite repair cap on an outer surface (22) of the composite stringer so that the composite repair cap extends over a damaged portion (12A) of the composite stringer. The compositerepair cap is then secured to the composite stringer to permit load transfer between the composite stringer and the composite repair cap.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 400,233, filed September 27, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to repairing structural components made of composite materials, and more particularly to composite stringers repairing the structures of aircraft and other mobile platforms. Background technique [0004] The use of composite materials is increasing in several industries. Some commercial aircraft incorporate components such as aircraft skin and other structural components such as stringers, which are made of composite materials because of their favorable mechanical properties and reduced weight. During manufacture or during service, composite stringers of an aircraft may be damaged by impact and may require repair. Traditional composite restoration methods can be relatively c...
