Abstract:

A process-property relationship analysis has been undertaken on a set of Axiom Material AX-7800 data obtained under a program to develop the framework for qualification of oxide/oxide ceramic matrix composite materials. The data show high variability in physical and mechanical properties, resulting in unacceptably low B-basis allowable when using the statistical methods defined in the Composite Materials Handbook CMH-17 Volume 5, Chapter 17. An analysis of the effects of processing variables and physical properties on mechanical properties has been completed. Least squares regressions and multivariate linear regressions were executed to evaluate these relationships. Additionally, microstructural evaluations were performed to support the analysis and root cause determinations of variability. Based on correlations observed between the data, acceptance limits for the physical properties of density, porosity, and per ply thickness are proposed that reduce the effective variability in the data without effecting a major change to the process specification.
