Abstract
The invention is a material for use in an inflatable aerodynamic braking device for a spacecraft. In detail, the invention includes a plurality of high temperature resistant barrier outer layers. Preferably, the outer layer is made of Aluminoborosilicate fabric. At least one carbon cloth layer is disposed behind said outer layers. A plurality of thermal radiation barrier intermediate layers are disposed behind the at least one carbon cloth layer. The intermediate layers include a plurality of metal foil layers, at least one additional carbon cloth layer interspersed between the metal foil layers. A plurality of metal-coated polymeric layers are disposed behind the metal foil layers, preferably a polyimide fabric coated with Aluminum. The metal foil layers are Aluminum and Titanium. At least one inflatable gas barrier interior layer is disposed behind the intermediate layers, preferably made of a polyimide material. The outer, intermediate and interior layers are sewn together by high temperature resistant thread, preferably Silicon Carbide thread.
