| 摘 要： | 采用阳极氧化法对PAN基高模碳纤维进行连续表面处理,重点研究了氧化电流密度对碳纤维宏观力学性能、表面形貌、表面酸性官能团以及碳纤维增强树脂基复合材料(CFRP)层间剪切强度(ILSS)的影响。结果表明,电流密度对纤维力学性能、表面形貌影响不大;氧化后纤维表面总的酸性官能团显著提高,最大增幅达13倍左右;适当的处理条件可使CFRP的ILSS从28.4 MPa提高到80 MPa以上。

| Abstract: | PAN-based high-modulus carbon fibers were continuously treated by anodic oxidation.The influence of anodic oxidation on macroscopic mechanical properties,surface morphology,surface acidic functional groups,interlaminar shear strength of the carbon fiber reinforced plastic(CFRP) was studied.In conclusion,macroscopic mechanical properties and surface morphology of CF were not influenced by anodic current density.After oxidation,the maximum amount of total surface acidic functional groups increased to 13 times that of untreated CF.Appropriate oxidative conditions could increase interlaminar shear strength from 28.4MPa to 80MPa. |
