摘　　要：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 ...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.
