摘要

Electrical resistance (ER) and acoustic emission (AE) have been proved to be the feasible approaches of real-time monitoring and evaluating damage in silicon carbide fiber-reinforced sihcon carbide (SiC/SiC) composites for a variety of loading conditions. In this study, they are used to monitor fatigue tests of two types of woven SiC/SiC composite systems with Hi-Nicalon type S (HNS) and Tyranno SA (SA) type fibers. Coupons, both at their pristine and post high-velocity impact states, are cycled under various loading frequencies ranging from 0.01Hz to 1Hz. Temperature effect is also considered, as tests were carried out at room temperature and elevated temperature (1200C). A critical ER value is introduced which can be used as an indicator for failure.
