Abstract
A corrosion barrier for use under heads of a plurality of friction elements in a structural assembly and a method of installing the corrosion barrier are provided. The corrosion barrier defines a plurality of spaced apertures extending along a length of the corrosion barrier and a corresponding plurality of perforations concentrically located around the spaced apertures. A plurality of friction elements within a corresponding plurality of spaced apertures in a corrosion barrier forms a friction element strip assembly that is loaded into two workpieces. The two workpieces are joined together after an area of corrosion barrier is removed.

A corrosion barrier for use under heads of a plurality of friction elements in a structural assembly, the corrosion barrier defining a plurality of spaced apertures extending along a length of the corrosion barrier and a corresponding plurality of perforations concentrically located around the spaced apertures.
A friction element strip assembly comprising:
- a plurality of friction elements;
- and
- a corrosion barrier for use under heads of the plurality of friction elements, the corrosion barrier defining a plurality of spaced apertures extending along a length of the corrosion barrier and a corresponding plurality of perforations concentrically located around the spaced apertures.
A method of installing a corrosion barrier under heads of a plurality of friction elements in a structural assembly comprising:
- loading a plurality of friction elements within a corresponding plurality of spaced apertures in a corrosion barrier to form a fastener strip assembly, the friction element strip assembly defining a corresponding plurality of perforations concentrically located around the spaced apertures;
- installing the friction element strip assembly to the two workpieces;
- and
- optionally removing an area of the corrosion barrier such that only a removable member between the apertures and the perforations remains under the heads of the friction elements.
