FAILURE CRITERIA FOR CARBON-CARBON APPLICABLE TO CONTOURED WOVEN ITE MATERIALS

THIS PROJECT WILL DEVELOP AN ANALYTICAL MODEL CAPABLE OF PREDICTING FAILURE OF CARBON-CARBON (C-C) MATERIALS. THE MODEL WILL BUILD UPON THE FIRM'S IN-HOUSE C-C ANALYSIS CODES AND WILL DEVELOP DEMONSTRATED CAPABILITY TO PREDICT FAILURE OF C-C COMPOSITES. IN PARTICULAR, METHODS FOR ANALYZING C-C MATERIALS, SUCH AS THE CONTOURED WEAVE DESIGNS BEING DEVELOPED FOR APPLICATION TO NASA'S ADVANCED SOLID ROCKET MOTOR, WILL BE DEVELOPED. VERIFICATION OF THE MODEL'S PREDICTIVE CAPABILITY WILL BE ACCOMPLISHED THROUGH CORRELATION OF EXISTING C-C EXPERIMENTAL DATA.
