SiCf/SiC复合材料的RMI制备方法以及微观结构和性能优化
Optimizing Microstructure and Properties of SiCf/SiC Composites Prepared by Reactive Melt Infiltration
摘要
Abstract
Reactive melt infiltration (RMI) is one of the most effective methods to prepare highly dense ceramic matrix composites. The melt infiltration and the formation of composites are mainly determined by the pore structure of preforms. Here, SiC fiber reinforced SiC matrix composites (SiCf/SiC) were prepared by infiltrating Si melt into carbon-contained preforms with various pore structures. Effects of pore structure on the melt infiltration and received SiCf/SiC composites were investigated. The results indicated that the preforms with more homogeneous pore size could lead to more sufficient melt infiltration, and also resulted in fewer residual pores and better mechanical properties in the composites. This study is expected to provide important guidance for the pore structure regulation in the fabrication of RMI-composites.关键词
