Abstract : Advanced composites will play a key role in the development of the technology required for the design and fabrication of future supersonic vehicles. However, implementation of the material into vehicle usage is contingent upon accelerating the demonstration of service capacity and design technology. Because of the added material complexity and lack of extensive service data, laboratory replication of the flight service will provide the most rapid method of documenting the airworthiness of advanced composite systems. A program is in progress to determine the time/temperature/stress capabilities of several high temperature composite materials. Tests included in this study are thermal aging, environmental aging, fatigue, creep, fracture, tensile, and real-time flight simulation exposure. The program has two parts. The first includes all the material property determinations and aging and simulation exposures up through 10,000 hours. The second continues these tests up to 50,000 cumulative hours. This report presents the results of the 10,000 hour phase, which has now been completed.
