Room and Elevated Temperature Tensile Properties of SiCf/TC17 Composite

摘要：

SiQ/TC17 composite was prepared from precursor wires produced by magnetron sputtering. The results showed that full density of the composites was achieved and no porosity was detected. The fibers were arranged well forming a nearly hexagonal array. The longitudinal tensile properties of the SiCr/TC17 composite have been investigated at room and elevated temperature. The tensile strength of the composite was significantly increased,to 1717 MPa and 1341 MPa at room temperature and 500℃ respectively,due to the incorporation of SiC fiber. Scanning electron microscopy (SEM) was used to study the matrix deformation, interfacial debonding and fiber pullout. Different damage models have been obtained by comparing the stress-strain curves and fractographs of tensile samples at room and elevated temperatures. The damage processes of SiC1/ TC17 composite under tensile loading at room and elevated temperature are discussed.
