Title: Design and Life Prediction Methodologies for Weight Efficient Ceramic Matrix Composite (CMC) Propulsion Components
Agency / Branch: DOD / NAVY
Contract: N68335-04-C-0109
Award Amount: $69,999.00
 

Abstract:

It is proposed to apply the capabilities of an award wining integrated life prediction software to a Ceramic Matrix Composite (CMC) nozzle. Previously verified on (CMC) combustor/blade-track, the software will perform: 1) material characterization analysis of 2D/3D CMC architectures at the constituent level to predict suitability of newly available CMC materials to their application, 2) material uncertainty analysis and sensitivities of mechanical properties to show the variation in the intensity of potential failure modes, 3) progressive failure analysis predicting critical damage events, failure modes, inspection points/intervals, fracture paths, and life cycles based on micro-crack damage evolution, and 4) life uncertainty analysis and life extension under all operational conditions including the effects of oxidation, extreme thermal environments, and manufacturing process anomalies/variabilities in voids, defects, textile-architectures, and ply-angles. This life prediction code is capable of evaluating CMC structures under static, dynamic, impact, creep, thermal, low/high cycle fatigue, and random power spectral density loads. The life prediction software will be validated using COIC-Oxide/Oxide, and GEAE-melt-infiltrated SiC/SiC coupon test data, and with documented uncertainties under static, creep, and fatigue load-spectra. Life prediction for nozzle design will reveal: Multi-site damage initiation/propagation locations, residual strength, micro-crack-density, and virtual non-destructive evaluation/inspection monitoring via exhausted energy release rates.
