摘要：
A simple bend stress relaxation (BSR) test has been developed to measure the creep-related deformation properties of ceramic fibers and whiskers. The test was applied to a variety of commercial and developmental Si-based fibers to demonstrate test capabilities and to qualitatively evaluate the relative creep resistance of the fibers at 1200-degrees and 1400-degrees-C. The implications of these results and the advantages of the BSR test over typical tensile creep tests are discussed.
