| Abstract: | The critical stress of stress solvent crazing, the morphology of stress solvent crazes of both oriented and non oriented aviaton organic glasses (DYB3 and YB3 for short respectively) and the effects of water and ultraviolet light on the two materials were studied. The improvement of orientation on the environmental stress cracking behavior of the organic glasses and and its mechanism were also discussed. |
