摘　　要：陶瓷基复合相变蓄热材料作为一种节能蓄热材料而备受关注.虽为一种功能复合材料其力学性能也应引起重视,特别是材料压制和烧结过程中应力集中现象,对材料的性能将产生重大影响.文章主要对陶瓷基复合相变蓄热材料压制与烧结过程的应力和应力分布进行了分析.As a heat-storing and energy-saving material, the phase change materials （PCMs） has drawn a great attention from both the academic and industrial sectors. Although it is originally a functional composite material, its mechanical properties should be given adequate attention. Particularly, stress concentration occurring in compression and sintering has significant influence on the material properties. The stress and stress distribution occurring during compression and sintering of the ceramic-matrixcomposite materials are elucidated in this paper.
