摘要: 以环硼氮烷为氮化硼陶瓷先驱体,2.5D石英纤维预制体为增强体,制备了2.5D石英纤维增强氮化硼陶瓷基(2.5D SiO2f/BN)复合材料。本文对环硼氮烷进行了结构表征,考察了2.5D SiO2f/BN复合材料的致密化效果、力学性能和介电性能。研究表明,2.5D SiO2f/BN复合材料外层致密,内部疏松多孔,具有优异的力学性能和介电性能,可用于天线罩透波材料。

Abstract: The 2.5D quartz fiber reinforced boron nitride ceramic matrix (2.5D SiO2f/BN) composites were prepared by using borazine as the boron nitride ceramic precursor and 2.5D quartz fiber preforms as the reinforcement.The structure characterization of borazine was performed. The densification effect, mechanical properties and dielectric properties of 2.5D SiO2f/BN composites were investigated. Experimental study shows that 2.5D SiO2f/BN composites have a dense outer layer and a loose, porous interior. They have excellent mechanical and dielectric properties which can be used for radome wave-transmitting materials.

Key words: quartz fiber, boronnitride, composite, wave-transmitting
