摘要：
We report test results using optical fiber sensors to measure dynamic strain and temperature on-ceramic-matrix composite (CMC)specimens at temperatures up to 600 degrees C. For strain sensing we are employing extrinsic Fabry-Perot interferometric (EFPI) strain gages fabricated with gold-coated optical fibers and attached to the CMC specimens using high-temperature ceramic adhesive. For temperature measurements, specially fabricated Bragg and long-period grating (LPG) sensors are being employed.
