A simple method is presented for measuring Young's modulus of a ceramic fiber, which is clamped horizontally as a cantilever beam and deforms due to its own weight. Young's modulus is calculated from the deflection at the cantilever tip according to the equation for large deflection of a cantilever beam with uniformly distributed load. The validity of this measurement method is demonstrated by comparing the test results at room temperature with those of tensile tests on ceramic fiber specimens. For both testing methods, the measured values agreed within 6%. SiC fibers are tested at elevated temperatures up to 1000℃. It is shown that Young's modulus of the fibers decreases with an increase in temperature.
