摘　　要：试验研究了真空压力浸渗法制造SiCp／LY12复合材料中预制件制备工艺各参数的影响。结果表明，采用正确的粘结剂和添加剂、适当的预制件成型压力及合理的焙烧规范，可以制备出低体积分数（Vf≈30％～35％）的复合材料．The fabricating process of SiC particle pre forms for SiC,/LY12 composite materials in vacuum pres-sure infiltration method were investigated. The results showed that the preforms with low volume fraction (30%～50%) of particles can be made by using special organic materials such as CMC - Na amylum, PVA and inorganicbinder such as Na2SiO3.
