Currently, difficulties in modeling non-linear behavior and damage modes of carbon-carbon (C/C) composites beyond simplified in-plane models prevent accurate assessment of bending load and thermal stress effects in interlaminar directions where the stress limits can be significantly lower than in-plane stress limits. To this end, the proposed Phase I SBIR program seeks to develop and refine a new feature for ABAQUS/Standard, using user defined subroutines, for improved modeling of non-linear behavior of C/C composites from limited material characterization data, develop missing data from empirical relationships and micromechanical models, consider multiple modes of damage beyond the standard in-plane damage modes to include interlaminar damage and incorporate aspects of thermal damage. These tools will be validated using published experimental data. Following the success of the Phase I program objectives, GHI will develop a Phase II plan which will enable the goal of experimentally validating and refining this new C/C composite modeling tool. Based on our previous experiences and our current computational and experimental capabilities, the goals set forth in this proposal are well within our abilities. More importantly, this work will be of great benefit to the Navy and to the future of C/C composite analysis and hypersonic flight as a whole.
