When the amount of flexible curing agent added to epoxy resin weight is 10 wt. %,the impact toughness and fracture toughness increases by 33. 3% and 96. 3%,respectively,compared with the pure epoxy resin. When the amount of flexible curing agent added to epoxy is 10 wt. %,the resulting impact toughness of the material is 19. 5k J·m-2at-50℃,the impact toughness of pure epoxy resin is only7. 96 k J·m-2.","PeriodicalId":22171,"journal":{"name":"Synthetic Materials Aging and Application","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86870309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
