Relation between the microscopic fracture pro cess of carbon epoxy composite laminates and their fracture toughness
環氧樹脂復合層板脫層破斷的微觀過程與斷裂韌性的關系Study on the optical properties of transparent epoxy / clay nanocomposites a new type transparent epoxy based nanocomposites has been prepared by the reaction of alkylammonium exchanged montmorillonite ( amt ) with diglycidyl ether of bisphenol a ( dgeba ) and triethylamine as the curing agent. the morphology of amt in the epoxy matrix was characterized with x - ray diffraction ( xrd ), scanning electron microscopy ( sem ) and transmission electron microscopy ( tem )
光學透明環氧樹脂粘土納米復合材料光學性能採用十八烷基伯胺鹽、十六烷基三甲基溴化胺處理na基蒙脫土製備出兩種不同的有機土，以三乙胺為固化劑，有機土與雙酚a型環氧樹脂熔融插層聚合后制備出剝離型和插層型兩種結構的環氧樹脂粘土納米復合材料。Epoxy resin / montmorillonite clay nanocomposite was prepared by intercalating with epoxy and organic montmorillonite clay, which was modified with the long chain quaternary ammonium salts with two positive ions in a molecule as the organic processing reagent
摘要採用雙子季銨鹽對蒙脫土進行有機化處理，再與環氧樹脂進行插層復合制備了環氧樹脂蒙脫土復合材料。Curing agents and mixing conditions were two important factors that effected on exfoliation behavior of organophilic montmorillonite in diglycidylether of bisphenol a matrix. the organophilic montmorillonite was exfoliated completely and there were no d001 diffraction peaks with methyltetrahydrophthalic anhydride as curing agent and benzyldimethylanine as catalyst. properties test results show that mechmical properties, electricity properties, heat distortion temperature of the exfoliated nanocomposites were all improved by addition of the montmorillonite, and the nanocomposites had lower linear thermal expansion coefficiency and water absorption compared with neat epoxy resin
結果表明，環氧樹脂與有機蒙脫土的相容性好；混合條件和固化劑是影響有機蒙脫土在環氧樹脂中剝離的兩個重要因素，在一定的混合條件下並選用合適的固化劑可以使蒙脫土在環氧樹脂中完全剝離；剝離型環氧樹脂蒙脫土納米復合材料的力學性能、電性能、熱性能以及吸水性能與純環氧樹脂固化物相比均有不同程度的提高和改善。分享友人
