Through Thickness Modulus (E33) of Ceramic Matrix Composites: Mechanical Test Method Confirmation (Preprint)

Abstract

Considering the interest in and challenges of using ceramic matrix composites, a full understanding of the physical properties is needed to continue to move the technology forward. A property of interest to the design process is the through thickness modulus of the composite and most high performance CMC material systems are produced extremely thin hindering generation of test specimens that can easily be instrumented and tested in the through-thickness direction. Past work by the authors has shown that a stacked disk method could measure the through thickness modulus at various temperatures with sufficient accuracy. Due to the nature of the stacked disk, several testing issues were present and a model material system was chosen to alleviate testing concerns. A monolithic ceramics system was used to verify the test method by using the material in its monolithic state deploying the same stacked disk method. Results and conclusions of this verification effort will be discussed.
