Both surfactants can intercalate into the layers of the pristine clay dispersed in water prior to polymerization. Although the d spacing of the POSS-intercalated clay is relatively smaller than that of the CPC-intercalated clay, PS more easily intercalates and exfoliates the POSS-treated clay than the CPC-treated clay.

插层剂预先插层到分散於水中的黏土后再进行乳化聚合反应，虽然POSS插层后黏土的层间距离较CPC插层后的层间距离小，但聚苯乙烯与POSS互容性较佳，所以易使黏土达到脱层结构，而CPC则反之。

Following conclusions are concerning the strength of filament wound solid rocket motor case:(1) The inter-delamination is important for the strength of the case, and there are many factors, such as, the matrix, the interface, the fiber volume fraction, the fiber arrange pattern, to influence on the delamination.

最终结合宏观、细观两方面的研究和分析，并联系到纤维缠绕固体火箭发动机壳体的强度，可以得到如下结论：（1）壳体的内部脱层是导致壳体强度下降的重要原因，而影响壳体内部脱层的因素除了基体材料外还有界面，纤维的排列阵列、体积分数，壳体的铺层次序等。

With analysing the the fatigue mechanism, the general mode of interply fatigue damage propagation is denoted by delamination length and crack density. Based on the power-law, the relationship between number of cycles and delamination length and crack density are established. The specimen is modeled as an equivalent six-ply material system. Starting with the analysis of interply stress, the interply shear stress under cyclic loading is calculated by using nonlinear three-demension FEA. According to the stage regularity of fatigue damage propagation, such models as average strain, effective modulus, ratio of delamination length and crack density, experimental relationship between crack density and effective modulus, are proposed by introducing subsection coefficient.
