摘　　要：以玻璃纤维为成孔剂,采用孔隙预置技术制备了发汗多孔C/SiC复合材料。对孔隙结构进行了表征,并研究了材料的力学性能和渗透行为。研究结果表明,采用孔隙预置技术能够有效地实现多孔C/SiC材料开孔率和孔隙结构控制,该材料具有良好的力学性能和渗透性能。The porous C/SiC composies was prepared by prefabricating pore media technology that adopt glass fiber as pore media, and its property was studied. The results showed that the technology can control the open porosity and the pore structure successfully by the volume content and distribution of glass fiber in the braids. The porous C/SiC composites have good mechanical properties and good infiltration property.
