Embodiment Construction

[0024]Referring more particularly to the drawings, embodiments of the disclosure may be described in the context of an aircraft manufacturing and service method 100 as shown in FIG. 1 and an aircraft 200 as shown in FIG. 2. During pre-production, exemplary method 100 may include specification and design 102 of the aircraft 200 and material procurement 104. During production, component and subassembly manufacturing 106 and system integration 108 of the aircraft 200 takes place. Thereafter, the aircraft 200 may go through certification and delivery 110 in order to be placed in service 112. While in service by a customer, the aircraft 200 is scheduled for routine maintenance and service 114 (which may also include modification, reconfiguration, refurbishment, and so on).

[0025]Each of the processes of method 100 may be performed or carried out by a system integrator, a third party, and / or an operator (e.g., a customer). For the purposes of this description, a system integrator may inclu...

Abstract

The different illustrative embodiments provide a method and apparatus for installing an edge seal. In one illustrative example, a pre-cured edge seal is placed on an edge of a composite structure with a sealant to form a placed pre-cured edge seal. The placed pre-cured edge seal is then cured on the composite structure.In another illustrative embodiment, an edge of a structure is prepared with solvent, and a brush coat of sealant is applied to the top and the edge of the structure. A fillet is applied to the base of the edge of the structure. A pre-cured edge seal is applied to the edge of the structure, and the edge is cured.

Description

BACKGROUND INFORMATION[0001]1. Field[0002]The present disclosure relates generally to composite components and in particular to a method and apparatus for manufacturing composite components. Still more particularly, the present disclosure relates to a method and apparatus for improving the method of edge sealing.[0003]2. Background[0004]Aircraft are being designed and manufactured with greater and greater percentages of composite materials. Some aircraft may have more than fifty percent of its primary structure made from composite materials. Composite materials may be used in aircraft to decrease the weight of the aircraft. This decreased weight may improve payload capacities and fuel efficiencies. Further, composite materials may provide longer service life for various components in an aircraft.[0005]Composite materials may be tough, light-weight materials, created by combining two or more dissimilar components. For example, a composite may include fibers and resins. The fibers and...
