| 摘 要： | 对比了采用先驱体浸渍法制备的三种不同纤维增强SiC基复合材料的性能差异,并从材料的微观结构特征入手分析了差异产生的原因。通过研究发现,采用Hi-Nicalon纤维增强的SiC基复合材料具有较好的性能,单向复合材料弯曲强度达到703.6 MPa, 断裂韧性达到23.1 MPa·m1/2;采用国产吉林碳纤维(JC)制备的SiC基复合材料也具有较好的性能,弯曲强度为501.1 MPa,断裂韧性为13.8 MPa·m1/2。

| Abstract: | The properties of three types of fibers reinforced SiC composite materials produced by polymer infiltration were compared and the cause of property differences was exposed via analysis of the microstructure of the materials. It was found that SiC matrix composite material reinforced by Hi-Nicalon fibre had the most preferable properties, uni-directional composite material of this type reached a bending strength of 703.6 MPa, and fracture toughness of 23.1 MPa·m1/2. Composite materials reinforced by JC carbon fibre had preferable properties too, with bending strength of 501.1 MPa, and fracture toughness of 13.8 MPa·m 1/2. |
