| 摘 要： | 研究了不同组成的NEPE推进剂/衬层粘接界面细观力学性能和结构的差异,以及对应粘接界面贮存过程中粘接性能和破坏方式的变化规律,探索了粘接界面的细观力学性能、结构与破坏方式的内在关联,初步提出NEPE推进剂/衬层粘接界面失效模式。试验结果表明,粘接界面细观力学性能、结构与界面粘接质量相关,是影响界面失效模式的主要因素。粘接界面具有高模量、高硬度层,N元素含量高且有明显梯度变化时,粘接质量较好,发生内聚破坏,反之发生界面破坏或混合破坏;老化过程中,粘接界面的模量和硬度降低、N元素的含量明显降低决定粘接界面依次发生内聚破坏、混合破坏和界面破坏。

| Abstract: | The diversities of microcosmic mechanical performance/structure in different bonded interface of NEPE propellant/liner and the rule of bonded performance and breakage modes were studied.The inhesion correlations between microcosmic mechanical performance/structure with breakage mode were researched.The prelimary failure mode of NEPE propellant/liner was put forward.The experimental results show that microcosmic mechanical performance/structure has inhesion correlation with the quality of interface and it is... |
