SiC界面涂层对碳纤维针刺毡增强Al 2 O 3 复合材料力学性能的影响(英文)
发布时间：2024-02-21 14:23
分别采用3D碳纤维针刺毡为增强体以及聚碳硅烷(PCS)衍生SiC涂层为界面相,通过溶胶-浸渍-干燥-热处理(SIDH)技术制备C/Al2O3复合材料,研究SiC界面涂层对C/Al2O3复合材料力学性能、抗氧化性能和抗热震性能的影响。结果表明,C/Al2O3复合材料的断裂韧性显著优于Al2O3单体陶瓷,引入SiC界面涂层后,尽管断裂功有一定程度下降,但C/Al2O3复合材料的强度得到明显提高;得益于SiC涂层和C纤维之间的强结合,C/SiC/Al2O3复合材料在静态空气中表现出明显优于C/Al2O3复合材料的抗氧化和抗热震性能。
