High Temperature Compression Testing Of Monolithic Silicon Carbide (Sic), Adam L. Mcnaughton
High Temperature Compression Testing Of Monolithic Silicon Carbide (Sic), Adam L. Mcnaughton
Electronic Theses and Dissertations
High temperature compression tests were administered in an oxidizing atmosphere on a commercially available monolithic (un-reinforced) reaction bonded silicon carbide (RBSiC) and an in-house processed silicon carbide based on a pre-ceramic polymer precursor. Ceramics such as silicon carbide have exceptional mechanical properties for both structural and thermal load applications. High tolerance specimen preparation via diamond wheel cutting and grinding to allow for compression testing on both types of silicon carbide ceramic at temperatures ranging from 20°C (68°F) to 1000°C (1832°F) is also addressed. Two types of specimen geometry were chosen due to the high strength and high stiffness of silicon …
