| 摘 要： | 通过对热塑性树脂PAEK增韧BMI树脂的玻璃化转变行为,相形貌和断裂韧性,以及对采用"离位"概念增韧的T700/BMI复合材料的层间形貌及其冲击后压缩强度(CAI)的分析,研究了微结构-性能之间的关系,发现特征相分离形貌随着PAEK的含量而变化。特别探索了PAEK-BMI复相体系的相形貌与断裂韧性之间的关系,得到的断裂机理解释了复合材料层压板的分层和冲击损伤行为。有关"离位"增韧的机理、以及扩散控制的相行为等还需要继续研究。

| Abstract: | The microstructure property relationships have been studied in terms of glass transition behavior,phase morphology,and fracture toughness on thermoplastic polyetherketone with a phenolphthalein side group (PAEK) toughened bismaleimdes (BMI) resins,and in terms of interlaminar morphology and compression after impact (CAI) on the graphite fiber (T700SC),the rein-forced BMI matrix composites that are toughened with a so-called ex-situ concept,respectively. The characteristic morphology spectrum has been found ... |
