Patent number: 11137014Abstract: A conductive fastening system, a fastened assembly, and a method of fastening an assembly composed of layers of carbon fiber reinforced plastic (“CFRP”) and/or metallic material includes fasteners with an electrically conductive coating and electrically conductive gap filler materials between the fasteners and sidewalls of holes formed through the layers of the assembly. The sidewalls of the holes are coated with the electrically conductive gap filler material by abrading, injection or spraying. The fasteners with the electrically conductive coating are inserted through the holes. The conductive coating on the fasteners and electrically conductive gap filler material work together to enhance electrical conductivity between the fastener and assembly. The conductive coating also acts as a lubricant to reduce the amount of force required to insert the fastener into the hole thereby reducing damage to the assembly.Type: GrantFiled: January 8, 2019Date of Patent: October 5, 2021Assignee: The Boeing CompanyInventors: Darrin M.

Patent number: 10501202Abstract: Ignition-quenching systems comprise an ignition-quenching cover configured to quench an ignition event in a combustible environment triggered by an ignition source associated with a fastener stack. The ignition-quenching cover comprises a porous body that is gas permeable and that has pores sized to quench ignition in the combustible environment. The ignition-quenching cover further comprises a cover attachment feature configured to mate with a fastener attachment feature of the fastener stack. The ignition-quenching cover is configured to cover the fastener stack, which may be associated with a potential ignition source that produces an ignition event in the combustible environment. The porous body may include one or more porous elements that may be formed of various polymeric, mesh, or fabric materials. The ignition-quenching cover may comprise a non-porous frame that is bonded to the porous body and that defines the cover attachment feature.Type: GrantFiled: August 23, 2017Date of Patent: December 10, 2019Assignee: The Boeing CompanyInventors: Christopher S.
