| Popis: | Silicon carbide (SiC) and silicon carbide fiber reinforced composites (SiC/SiC f ) are currently being evaluated as a high temperature material for use in nuclear reactors. While methods to determine the mechanical properties of SiC/SiC f on planar test specimens are well established, mechanical testing methods for tubular SiC/SiC f are still being developed. In this study the C-ring test is evaluated for use with nuclear grade SiC/SiC f as a method of measuring hoop strength. For the samples tested in this work, hoop strengths from C-ring testing are shown to agree within 6% to those obtained using expanding plug testing and analysis shows that the expected composite behavior is observed during testing. While other techniques may give more accurate values for hoop stress, the small specimen requirements and ease of testing makes C-ring testing a valuable tool. |
