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° and 1400°C. The implications of these results and the advantages of the BSR test over typical tensile creep tests are dicussed.
