中文摘要:
      采用反应熔渗法将熔融Si渗入C/C多孔体中制备了C/SiC复合材料。研究了包埋式布硅对C/C多孔体不同位置毛细吸附行为的影响以及对制备C/SiC复合材料密度的影响。反应熔渗制备的C/SiC复合材料内部存在残余的游离硅,经过除硅处理后游离硅显著减少,但其致密化程度有所降低,同时其弯曲强度明显下降。
Microstructure and Properties of C/SiC Composites Prepared by Reactive Melt Infiltration
英文关键词:Reactive  Melt Infiltration (RMI), C/SiC  composites, Free  Si
英文摘要:
      C/SiC composites were prepared by reactive melt infiltration (RMI) of molten Si into the C/C porous preform. Influences of C/C porous preform embedded in silicon powder at different positons on the capillary absorption behaviors were investigated. Lots of free Si can be found inside of C/SiC composites prepared by RMI. The free Si was decreased significantly after desilication treatment of C/SiC composite, the composite density and flexural strength decreased as well.
