Patent number: 8766108Abstract: A composite gasket for sealing and EMI shielding is provided. The gasket has a resilient conductive mesh sheet embedded with an elastomer gel layer. The conductive mesh is corrugated to provide a series of repeating waveforms, providing the gasket with a lower deflection force, better corrosion resistance, and a higher EMI shielding capability. A second elastomer can be used around the edge portions of the gasket for improved abrasion resistance and increased tensile strength. A fiberglass sheet can be incorporated in the mesh for added reinforcement and support. The gaskets of the invention can be used on external aircraft components, such as external aircraft antenna mounts.Type: GrantFiled: May 9, 2011Date of Patent: July 1, 2014Assignee: Parker Hannifin CorporationInventors: Michael H. Bunyan, George R. Watchko, William G. Lionetta
