摘　　要：在弹性力学圆筒理论和剪滞模型的基础上，依据考虑界面相和界面层效应的力学简化模型，分两种情况具体讨论复合材料制备过程中由于降温落差大小造成的工艺残余应力，并与Ｂｕｄｉａｎｓｋｙ等人的结果作了对比讨论。第一种情况考虑了界面层剪切效应，第二种略去了界面层剪切效应。为了更清楚地了解界面间正压力与剥离力之间的区别，分αｆ＞αｍ和αｆ＜αｍ两种情况来分析。Thermal stress due to temperature change during fabrication of fiber-reinforced ceramic composites has been analyzed on the basis of elastic cylinder theory and shear-lag model.We further contemplete two distinct situations based on the new model that considers interface layer mechanical and thermal properties effects,(i) consider the interface shear effect,(ii) not consider the interface shear effect.Finally, we compared it with BHE’s results.
