Titanium matrix composites (TMC) are being evaluated for use in advanced hypersonic vehicle applications. The structural components in such applications are subjected to complex thermal and mechanical loading histories. To simulate service conditions, it is essential that thermomechanical fatigue (TMF) test techniques are developed and implemented. In this study, a versatile TMF testing facility used to conduct hypersonic flight profile simulation testing on TMC is outlined. The mechanical loading system of this TMF setup is controlled by a load profiler and consists of a closed loop, servo-hydraulic test frame equipped with water cooled hydraulic grips and a high temperature quartz rod extensometer. The thermal loading system consists of an induction heating system and a combined gaseous and liquid nitrogen cooling system controlled by a temperature profiler. Both the mechanical and thermal loading system are interfaced for synchronous operation and are connected to a data acquisition system. To demonstrate the capabilities of this TMF test setup, experimental stress-strain response of a cross-ply SCS-6/Timetal-21S TMC subjected to a complex TMF hypersonic flight profile with the temperature ranging from -130 deg C to 816 deg C will be presented.
