Abstract : An evaluation was done of the characteristics of fiber reinforced ceramics in radiation thermal protective structures acting as exterior radiation cover plates. Using as a basis typical mechanical environments and thermal environments associated with returnable spacecraft, experimental research was carried out with regard to carbon fiber reinforced quartz-- including such items as small plate reentry thermal simulation tests as well as room temperature vibration, room temperature shock, low temperature vibration, and low temperature shock associated with large scale thermal structural members, along with reentry heating, and so on. A series of tests clearly demonstrated that carbon fiber reinforced quartz not only retain%d ceramic resistance to high temperatures and good insulation characteristics, but also overcame inherent ceramic brittleness. As a result, it possesses considerable potential to act as thermal protective material on returnable spacecraft. (MM)
