Patent number: 6083615Abstract: A structure is formed of at least two structural elements that are bonded together with an electrically conductive organic adhesive system. The adhesive system is a mixture of an organic adhesive such as a thermosetting epoxy and a filler of electrically conductive carbon particles having a porous, sponge-like structure. In one application, the structural elements are exterior panels of a spacecraft coated with an electrically conductive paint, and in other applications the structural elements are not coated. The adhesive system permits static electrical charge to flow through otherwise insulated joints to equalize the static potential throughout the structure and eventually to dissipate the charge.Type: GrantFiled: July 16, 1997Date of Patent: July 4, 2000Assignee: Hughes Electronics CorporationInventors: Lynn E.
