| Research Abstract |
In this study, development study on high temperature ceramic based composite which can use in the temperature range over 2000K where SiC based composite could not survive. Carbon fiber reinforced three phase Zr based ceramics (ZrB2, ZrC and SiC) matrix composite with various composition was processed by plane woven carbon fiber cloth laminates through Si impregnation technique. Oxidation resistance was examined by H2/O2 gas burner rig test. Mechanical properties and Oxidation resistance of the composite was examined and the three phase ceramics matrix composite exhibited superior oxidation resistance than SiC matrix composite. Carbon fiber preform for a sub sized thruster successfully processed by three axes braiding technique. Composite thruster could not made for firing test to show its performance. However, the composite process established for a plate shaped composite panel could be adapted to the thruster shape. Finally all technical challenging issues had been cleared.
