Heat+shield

[|Heat shield] - designed to shield a substance from absorbing excessive heat from an outside source by either dissipating, reflecting or simply absorbing the heat. It is often used as a form of exhaust heat management.

Spacecraft
 * [|NASA's Orion spacecraft] - the heat shield must be capable of withstanding the intense pressures of re-entry into Earth's atmosphere at roughly 20,000 mph (32,187 km/h), and to withstand temperatures exceeding 4,000 ºF (2,204 ºC). The five-meter (16-ft) wide heat shield for the crew module of the Orion spacecraft, is comprised of silica fibers with an epoxy-novalic resin filled in a fiberglass-phenolic honeycomb.
