| description | <p><strong>Background:</strong> Ceramic matrix composites are promising materials for high temperature application in aerospace and nuclear engineering. In these applications, thermal shock is an important potential cause for failure.</p>
<p><strong>Objective:</strong> In order to study thermal shock resistance of SiC/SiC composite braided tubes, a novel method has been developed to apply thermal shock cycles to tube sections and then measure the residual tensile strength.</p>
<p><strong>Methods:</strong> SiC/SiC composite braided tubes have been thermally shocked by many cycles in a short time using a novel test platform based on quartz lamp irradiation heating. The circumferential tensile strength was measured using C-ring specimens after thermal shock testing of short tube sections. Numerical simulations of the stress from the thermal shock test were conducted using the finite element method.</p>
<p><strong>Results:</strong> The circumferential tensile strength decreased with increasing number of thermal shock cycles in air. An embrittled region with limited fiber pullout due to oxidation extended from the surface.</p>
<p><strong>Conclusions:</strong> The test platform can simulate service environments with fast temperature cycling for small test specimens in air.</p> |
