Abstract:

As ceramic matrix composites are being targeted for aerospace applications, key material properties need to be understood. This is especially true since the current 2-D architecture-based materials are fabricated by stacking plies that are prime paths for delaminations. Hence, an effort to understand the current test method for delamination toughness was initiated. Specifically, interest was in using a notch for the test and not a starter crack. A model ceramic matrix composite of a SiC fiber with a polymer infiltration pyrolysis derived ceramic matrix was used in this investigation. This material was machined as a double cantilever beam specimen. Testing was done under displacement control. This effort will discuss the testing and analysis of the double cantilever beam specimen.
