摘要:
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.

A phased array antenna radiator assembly that in one embodiment has a thermally conductive foam substrate, a plurality of metal radiating elements bonded to the foam substrate, and a radome supported adjacent the metal radiating elements. In another embodiment a phased array antenna radiator assembly is disclosed that has a thermally conductive substrate, a plurality of metal radiating elements bonded to the thermally conductive substrate, a radome supported adjacent the metal radiating elements, and an electrostatically dissipative adhesive in contact with the radiating elements for bonding the radome to the thermally conductive substrate.

摘要:
The present invention is related to heat transfer materials including nano-scale boron nitride platelets having an aspect ratio ranging from about 10:1 to about 1000:1. The present invention also provides a method of removing heat from an object by directly or indirectly contacting the object with the heat transfer materials.
