UTC has been awarded the Assessment of Damage Progression Models for SiC/SiC Ceramic Matrix Composites (CMC) effort. This program will assess and quantify the effectiveness of progressive damage models (PDM) for prognosis of behavior and life of SiC/SiC ceramic matrix composites in application relevant environments. In addition, the utility of PDM models for damage tolerance base assessment of CMC based aero-components will be demonstrated.
Dr. Rollie Dutton, UTCs Director, Materials and Manufacturing stated; “our Principal Investigator, Mr. Larry Zawada, has an extensive background in CMCs and is excited to get started on this effort. We appreciate this opportunity to contribute to this important work for the Air Force Research Laboratory (AFRL), Materials and Manufacturing Directorate, Composites Branch”.
UTC will characterize SiC/SiC CMC coupon properties via appropriate coupon testing or data supplied from the manufacturer; calibrate a selected set of currently available PDMs with coupon data; predict feature tests without available experimental results with calibrated PDM models; validate the PDM predictions of the feature tests through appropriate experiments; and mature PDM approaches to address any deficiencies identified through the validation tests.
This efforts continues UTCs extensive research portfolio for the AFRL Materials and Manufacturing Directorate.
