Abstract: A fiber-reinforced composite structure includes a cut edge; an elastomeric cap covering the cut edge; and an adhesive sealant bonding the elastomeric cap to the cut edge. The fiber-reinforced composite structure is joined to a component and the elastomeric cap includes a generally Z or L-shaped cap with a web bonded to the cut edge of the fiber-reinforced structure and a flange bonded to the component and extending away from the fiber-reinforced structure.

Abstract: An aircraft component with an aerodynamic surface coating comprising a resilient foam with an array of open cells infused with a cleaning material such as a gel, paste or liquid. This prevents contaminants such as insects from adhering to the aircraft component. The resilient foam stores at least part of the impact energy of the contaminant, the cleaning material is released from the deformed foam so that the cleaning material at least partially coats the contaminant, and the foam springs back to eject the coated contaminant from the aircraft component.
