Award Description: Title: Advanced Material Propulsion Initiative (AMPI) Advanced Non Destructive Evaluation (NDE) for Ceramic Matrix Composites (CMCs) - Addendum 2: Effects of Defects Study Program. The purpose of the AMPI program is to improve CMC manufacturing processes through the use of NDE technologies that will result in increased yields and quality while reducing costs and processing times. A major impediment to full implementation of CMC materials into aerospace applications is the lack of data and models linking measurable defects parameters to thermo-mechanical behavior and subsequent failure. To address this impediment, work has been funded under the American Recovery and Reinvestment Act to conduct an effects of defects study on CMC materials by creating specimens with known defects and correlating these with mechanical property data derived from thermo-mechanical tests. The test results will also assist in the validation of numerical models for these materials. An additional goal is to down select specific NDE technologies for manufacturing quality inspections for CMC production process. The primary deliverable of the program is a final report detailing: 1) the mechanical tests conducted and assessments of the effect of the defects on the behavior of the material tested, and, 2) the NDE processes evaluated with recommendations for the processes that can meet the performance, cost and technical maturity requirements for manufacturing quality inspections of CMCs. In support of the overall objectives of this program, the major outcomes are: - Quantification of the effect of selected defects on material properties. - Evaluations of the NDE processes and identification of the output requirements necessary to ensure successful detection of parameters critical to defect characterization. - Recommendations for implementation of an appropriate NDE inspection method into production for material quality assessments.
