The demanding environment in aircraft turbine engines has driven the development of many innovative high temperature materials. This thesis examines one of the latest of these materials, an oxide/oxide ceramic matrix composite (CMC), N720/A. This CMC consists of a porous alumina matrix reinforced by Nextel 720 fibers in a balanced 8 harness satin weave. To characterize this material, monotonic tensile and cyclic fatigue tests were performed at room temperature and at 1200 . The effects of moisture on fatigue behavior were also investigated at 1200 . Modulus, maximum and minimum strain and stress strain hysteresis were monitored during the cycling to characterize fatigue damage mechanisms. Retained strength of all specimens that survived I Os cycles was also characterized. Microscopy and fractography were used to examine microstructure, damage mechanisms, and fracture surfaces. N720/A was found to have good room temperature and high temperature properties.
