Ceramic matrix composites properties/microstresses with complete and partial interphase bond

摘要: A multilevel substructuring technique which includes a unique fiber concept is used for the analysis of continuous reinforced ceramic matrix composites. This has four levels substructuring--from laminate to ply, supply, and then fiber. stand-alone computer code CEMCAN (Ceramic Matrix Composites Analyzer), incorporating this specifically simulation composites behavior, currently under development at NASA Lewis Research Center in Cleveland, Ohio. The thermal mechanical properties, along with microstresses, SiC/RBSN (silicon carbide reaction bonded silicon nitride matrix) composite different volume ratios varying degrees interfacial bond around circumference are computed. Values predicted by shown bound experimentally measured values. Results also show that transverse tensile strength test can be sensitive method assess conditions.
