Patent ID: 11892035

Abstract:
A composite/metal joint includes a composite member, a metallic member, a cylindrical liner, and a fastener. The composite member has a first aperture. The metallic member is disposed adjacent to the composite member and has a second aperture coaxially aligned with the first aperture. The cylindrical liner extends longitudinally from a first end to a second end. The cylindrical liner has a cylindrical outer liner surface and a longitudinally extending third aperture coaxial with the first and second apertures and defined by an inner liner surface. The cylindrical liner is disposed in the first and second apertures with the outer liner surface adjacent to aperture walls of the first and second apertures. The cylindrical liner has a plurality of grooves intersecting the outer liner surface. The fastener is disposed through the third aperture of the cylindrical liner and is configured to attach the metallic member to the composite member. An outer surface of the fastener is in direct contact with the inner liner surface.
