Abstract
A laminate (10) which is transparent to radio frequency emissions, useful as a thermal control and electrostatic discharge surface, for example for protecting spacecraft antenna hardware, comprises a conductive layer (12) for dissipating electrostatic charges and a thermal control layer (24) for reflecting thermal radiation and reducing the effect of temperature variations on one side of the laminate on the region on the other side of the laminate. In a preferred embodiment, the conductive layer (12) preferably comprises a semiconductor, such as germanium. The thermal control layer (24) comprises a film layer (14), for example of polyimide film, a mesh layer (16), for example of polyamide fabric, attached to the film layer (14), and a thermally reflective coating (20), applied to the mesh layer (16) for aiding the conductive layer (12) and thermal control layer (24) in reflecting radiation.
