“…Therefore, these test methods are not as sensitive to the type of damage development seen in glass-ceramic composites as methods based on measuring thermal or elastic properties. It has been shown in several studies that changes in elastic and thermal properties were observed well before strength degradation following thermal shock [12,13]. Residual strength tests were not performed in this study due to the sample geometry, but would be valuable in comparing the sensitivity of the methods to microstructural damage development.…”

The effect of thermal shock and oxidation-induced damage on the thermal diffusivity of unidirectional Nicalon-LAS glass-ceramic composites is presented in this study. The data presented show that thermal diffusivity measurements provide a sensitive nondestructive method whereby damage progression may be assessed. Samples were exposed to isothermal oxidation and thermal shock environments. In addition, combined cycles of oxidation and thermal shock were also evaluated. The thermal diffusivity transverse to the fibers was measured to detect changes in material integrity. Significant decreases up to 23% were observed in the thermal diffusivity of the material.

The material investigated in this study is a prototype material, where a low density and highly porous carbon-carbon composite, termed carbon bonded carbon fibre (CBCF), has been given a protective coating of silicon carbide using chemical vapour deposition. The aim of the current study was to gauge the effectiveness of the silicon carbide coating in protecting the CBCF materials from degradation within an oxidising atmosphere. Avenues of investigation included assessing the behaviour of the materials when heated to elevated temperatures within an oxidising environment (using thermogravimetric analysis and bulk oxidation tests) and also evaluating the residual strength of the composites after subjection to thermal shock/cycling. It has been found that the performance of the CBCF material in oxidising conditions has improved with the incorporation of the silicon carbide coating and also that the coated material is resilient against thermal shock/cycling.
