A Technique for Tensile Fatigue and Creep Testing of Fiber-Reinforced Ceramics

Abstract

An experimental technique for the elevated temperature tensile fatigue and creep testing of fiber-reinforced ceramics is discussed. The experimental approach utilizes edge-loaded specimens with rectangular gage-sections. Novel furnace and grip designs which allow testing in air to 1500°C are provided. The specimen, furnace and grip designs discussed in the paper have been successfully used to test unidirectional and cross-ply SiCf/Si3N 4, SiCf/SiC, Cf/SiC and SiCf/calcium-aluminosilicate composites.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66679/2/10.1177_002199839202600608.pd
