以普通纸张为原料,采用凝胶-溶胶技术对纸张进行处理,并通过折叠、粘贴等仿生设计,经低温炭化、高温碳热还原反应及气相渗硅等方式制备出SiC/Si蜂窝陶瓷载体复合材料.采用XRD、SEM、TEM和三点弯曲等分析测试手段对其相组成、微观结构和力学性能进行分析.结果表明,陶瓷纸炭化以后为非晶态的碳;经真空炉烧结后的相组成为β-SiC相、Si相和残留的C相.三点弯曲实验表明,SiC/Si陶瓷复合材料的强度超过200MPa.多孔碳化硅的气孔率随着排硅时间的增加而增加,其强度和韧性随着排硅时间的增加而减小.%The ordinary paper which handled by sol-gel technology,folding,pasting,bionic design and the technique of the low-temperature carbonization,high-temperature reduction carbonization and vapor silicon infiltrating, can be turned into the SiC/Si honeycomb ceramics carrie. Then the results of XRD, SEM.TEM,three-bending tests show that,the ceramic paper appears as amorphous carbon after carbonization, and the phase composition changed to β-SiC, Si, and C after silicon infiltrating in the vacuum environment, the bending strength of SiC/Si honeycomb ceramics carrier is 200MPa. The more silicon removing time is, the porosity of porous SiC will be increased, while it's strength and toughness will be decreased.
