Summary

The pursuit of any Next Generation Super Sonic Transport (NGSST) must meet two goals: it must be economical and it must be environmentally friendly. The use of advanced materials is key to achieving these goals. Advanced materials such as Ceramic Matrix Composites allows propulsion components to be fabricated that reduce or eliminate cooling air and allow higher gas-firing temperatures. Silicon Carbide/Silicon Carbide CMC is an excellent candidate for gas turbine engine applications in the combustor and turbine. This is based on its high temperature capability. Three panels of a 3-D orthogonal weave were fabricated and tested for through thickness thermal conductivity and tensile capability. Additional thermal and interlaminar testing was done on only two of the panels. Limited tensile testing at elevated temperatures showed initial indications for an ultimate temperature capability. The through thickness thermal conductivity showed that the material was very susceptible to matrix additions. The testing showed that the 3-D weave allows for improvements in interlaminar capability over 2-D weaves as expected. The results achieved to date will be discussed.
