Abstract:

Novel ceramic matrix composite tubes for deep submergence pressure vessel applications have been fabricated by the DIMOX directed metal oxidation process. These silicon carbidesaluminum oxides composite tubes have an eight percent lower weight to displacement ratio, approximately five times greater thermal conductivity, and more than 50 higher fracture toughness than a tube fabricated from alumina ceramics. Additionally, the SiCAl2O3 composite tubes have a sixty percent lower weight to displacement ratio and a 12 times greater thermal conductivity than titanium--gallium--4 vanadium alloy tubes. Processing information, hydrostatic implosion test results, and mechanical test data will be discussed.
