Three-dimensionally reinforced carbon-fiber-reinforced carbon matrix (3D-C/C) composites have been applied to the nozzle throats of solid propellant rockets such as SRB-A and M-V due to the excellent heat resistance at elevated temperatures. In order to assure the design reliability of the nozzle throats, the mechanical properties of the 3D-C/C composites are necessary from room temperature to elevated temperatures. However, no well-developed test method is available at present to evaluate the mechanical properties. The objective of this research is therefore the standardization of the test methods for evaluating the mechanical properties of the 3D-C/C composites. The mechanical tests discussed in this research include tensile, compressive and shear tests of the 3D-C/C composites from room temperature to elevated temperatures exceeding 2273 K.
