Hypersonic research efforts are currently increasing as there is a race to develop hypersonic vehicles. Currently, ceramic matrix composites (CMCs) are one of the leading materials of interest for these applications; however, due to their complexity, large amounts of testing must be conducted to further understand their behavior under such conditions. A versatile burner rig facility consisting of a high velocity oxygen fuel (HVOF) torch, capable of reaching extreme temperatures (> 2200 °C) and nearhypersonic velocities (~Mach 4.9), has recently been developed at the University of Akron [1]. In this work, several CMC systems were tested at ~Mach 4.9 and 1650 °C for a total of 10 minutes. Residual strength tensile and flexural tests were conducted after burner rig testing in order to determine the loss of strength and modulus. Electrical resistance (ER) was used alongside these tests as a non-destructive evaluation tool. The results showed large amounts of mass loss in several of these composite systems, especially those containing carbon fibers and interphases, as well as significantly reduced strength and modulus. Resistance change during burner rig testing was correlated to oxidative damage via mass loss and temperature change. A resistance model was developed for one of the composite systems that estimated the change experienced during burner rig testing due to oxidation of carbon fibers. Finally, samples were sectioned and polished to analyze the damage incurred during burner rig and residual strength testing
