中文摘要：

混合烧结法与熔融浸渍法是目前复合蓄热材料的两种基本制备方法，自发浸渍法是无机盐／多孔基体复合蓄热材料较佳的制备工艺。结合自发浸渍工艺原理的分析，对蜂窝陶瓷、添加造孔剂制备的多孔陶瓷与纤维多孔陶瓷在孔隙率、孔结构及力学性能等方面进行了比较。纤维多孔陶瓷凶其高孔隙率（可达95%以上）、优良的连通孔结构及特殊的断裂力学性能，可用作复合蓄热材料基体。纤维多孔陶瓷用于复合蓄热材料基体可有效地解决普通多孔基体中相变材料含量低、熔融物易溢出及抗热震稳定性差等问题。

英文摘要：

Mixed sintering and melting impregnation are the two basic preparation methods for composite heat storage materials, and the spontaneous immersion method is better for preparation of inorganic/porous composite heat storage material. Integrated analysis of the principle of spontaneous impregnation, porosity, pore structure and mechanical properties was conducted on honeycomb ceramic, porous ceramic made by adding pore-forming agents and fibre-reinforced porous ceramic. The fibre-reinforced porous ceramic can be used as composite heat storage materials’matrix, because of its high porosity （95%）, fine pore structure and special fracture strength. If used as composite heat storage materials’ matrix, the fibre-reinforced porous ceramic can be effectively used to solve low content of phase change materials, melt overflow and poor thermal shock resistance of common porous matrix.
