中文摘要	the static and impact fracture toughness of phenolphthalein polyether ketone (pek-c) were studied at different temperatures. the static fracture toughness of pek-c was evaluated via the linear elastic fracture mechanics (lefm) and the j-integral analysis. impact fracture toughness was also analyzed using the lefm approach. temperature and strain rate effects on the fracture toughness were also studied. the enhancement in static fracture toughness at 70 degrees c was thought to be caused by plastic crack tip blunting. the increase in impact fracture toughness with temperature was attributed two different mechanisms, namely, the relaxation process in a relatively low temperature and thermal blunting of the crack tip at higher temperature. the temperature-dependent fracture toughness data obtained in static tests could be horizontally shifted to match roughly the data for impact tests, indicating the existence of a time-temperature equivalence relationship.
