本研究采用原位生长的碳化硅纳米线(SiCnws)对碳纤维/碳化硅复合材料进行改性。通过与常规碳纤维/碳化硅复合材料的对比，研究了碳化硅对复合材料抗弯强度和断裂韧性的影响。结果表明，SiCnW显著提高了碳纤维/碳化硅复合材料的强度和断裂韧性。与Cf/SIC相比，Cf/SiCnw/PYC和Cf/SiCnw复合材料的弯曲强度分别从363.1 Mpa提高到375 Mpa和466.9 Mpa。含SiCnw的Cf/SiC复合材料在高温(1000 °C)下的抗弯强度和断裂韧性分别为565 Mpa和20.30 M1/2。这两个数值分别比传统的碳纤维/碳化硅复合材料提高了13.2%和16.1%。后者归因于碳化硅纳米线的偏转、桥联和拔出导致裂纹。改性碳/碳化硅复合材料力学性能的提高主要归因于碳化硅纳米线在裂纹上的偏转和桥联以及碳化硅纳米线从基体中拔出。
In this study, Cf/SiC composite was modified with SiC nanowires (SiCnws) grown in-situ in SiC matrix. Effects of SiCnwon bending strength and fracture toughness were investigated by comparison with conventional Cf/SiC. Results showed that SiCnwsignificantly improved both strength and fracture toughness of Cf/SiC. Compared to Cf/SiC, flexural strengths of Cf/SiC-SiCnw/PyC and Cf/SiC-SiCnwcomposites increased from 363.1 MPa to 375 MPa and 466.9 MPa, respectively. Bending strength and fracture toughness were estimated to 565 MPa and 20.30 MPa m1/2for Cf/SiC containing SiCnwat high temperature (1000 °C), respectively. These values were 13.2% and 16.1% higher than that of conventional Cf/SiC. The latter was attributed to deflection, bridging, and pull-out of SiC nanowires to cracks. Improvements in mechanical properties of modified C/SiC composites were mainly attributed to deflection and bridging of SiC nanowires on cracks and pulling out of SiC nanowires from the matrix.
