SWCNTs/环氧/双马来酰亚胺结构胶膜的制备与性能研究OA
Preparation and Properties Study of SWCNTs/Epoxy/Bismaleimide Structural Adhesive Films
利用环氧树脂对双马来酰亚胺树脂进行增韧改性,并制备环氧/双马胶膜.在树脂体系中加入单壁碳纳米管(SWCNTs),研究SWCNTs对环氧/双马胶膜结构与性能的影响.结果表明:当SWCNTs质量分数为0.007 5%时,胶膜的拉伸剪切强度达到最大值30.9 MPa,剥离强度为48.9 N·mm/mm.研究发现,经SWCNTs改性后,胶膜的玻璃化转变温度提高,耐热性上升,胶膜的断面形貌由改性前的脆性断裂转变为韧性断裂.
Epoxy resin was used to toughen bismaleimide resin and to prepare epoxy/bismaleimide adhesive films.Single-walled carbon nanotubes(SWCNTs)were incorporated into the resin system to investigate their effects on the structure and properties of the epoxy/bismaleimide adhesive films.The results showed that when the mass fraction of SWCNTs was 0.007 5%,the tensile shear strength of the adhesive film reached a maximum value of 30.9 MPa,and the peel strength was 48.9 N·mm/mm.It was found that after modification with SWCNTs,the glass transition temperature of the adhesive film increased,and its thermal resistance improved.The fracture morphology of the adhesive film changed from brittle fracture before modification to ductile fracture.
