| 摘 要： | 采用高压静电纺丝法制备了含多壁碳纳米管(MWCNTs)的聚醚酰亚胺(PEI)纳米纤维取向薄膜, 用SEM和TEM观察其微观形貌。将PEI纳米纤维薄膜铺放于环氧树脂中, 通过实验测试其冲击和拉伸性能。结果表明, 含MWCNTs的PEI纳米纤维膜对环氧树脂具有良好的增韧效果。Ⅰ型层间断裂韧性(GIC)测试表明, 用含质量分数3%活性碳纳米管(a-MWCNTs)的PEI纤维膜对T700碳纤维/环氧树脂复合材料进行层间增韧能够明显改善其层间断裂韧性。

| Abstract: | Polyetherimide (PEI) nano-fibrous membranes with multi-walled carbon nanotubes (MWCNTs)were prepared by electrospinning. The morphology of nano-fibrous membranes was studied by SEM and TEM. The impact and tensile properties of epoxy toughed by nano-fibrous membranes were investigated. The result shows that the toughness of epoxy is improved with the loading of PEI nano-fibrous membranes with MWCNTs. The result of G IC test shows that interlaminar fracture toughness of the carbon fiber/epoxy composites toughed by PEI nano-fibrous membranes containing 3% mass fraction active MWCNTs (a-MWCNTs) can be highly enhanced. |
