燃烧合成Cf/TiC-TiB2陶瓷基复合材料的致密化因素探讨

Densification factors of C_f/TiC-TiB_2 ceramic composites by combustion synthesis

用燃烧合成的方法合成出不同碳纤维含量的Cf/TiC-TiB2陶瓷基复合材料。简述了试验过程,详细研究了影响产品致密度的主要因素。通过理论和测试结果分析,预制坯的致密度、延迟时间td、高压压力P2、高压保压时间tp以及碳纤维的含量等都直接影响产品致密度,进而影响产品的性能。

Cf/TiC-TiB2 ceramic matrix composites with different Cf content was produced by combustion synthesis. The experiment process was presented. The main factors influencing the relative density was studied in detail. Test results show that relative density of preform,delay time td, high pressure P2, pressure maintaining time tp and C4 content influence directly the relative density and properties of product.
