This paper is a study by means of unnolched series impacting tests for some EP polymers at different temperatures, dealing with the effects of temperature and composition on the impact fracture. The results show that there is an extreme value on impact strength against temperature. And the hard particles of the second phase can enhance the impact strength of brittle materials while they induce the fracture origin initiating.
