| 中文摘要: |
| 为了减小碳纤维丝束在织造时与综丝眼摩擦产生的损伤，课题组提出了在综丝眼内镀有色金属铜的方法。先计算出开口过程中碳纤维丝束与综丝眼摩擦的动程，选取部分动程进行损伤分析，利用体积单元法对碳纤维丝束建立简化模型并在有限元软件ABAQUS中对该模型进行拉伸仿真分析；然后进行碳纤维丝束的拉伸实验并将仿真结果与实验数据相比，验证了丝束模型的正确性。课题组利用渐进损伤模型分析了碳纤维丝束与不同金属材料摩擦时的损伤情况，表明镀铜后的综丝眼与碳纤维丝束的摩擦损伤较小。 |
| 英文摘要: |
| In order to reduce the damage caused by friction between carbon fiber bundle and heddle eyes during weaving, a method of non ferrous metals copper plating in heddle eyes was put forward. The stroke of friction between carbon fiber bundle and heddle eyes during the opening process was calculated first and partially selected for damage analysis. The simplified model of carbon fiber bundle was established by unit volume method and the model simulation analysis was carried out by the finite element software ABAQUS. The simulation results were compared with the experimental data to verify the correctness of the model. The progressive damage model was used to analyze the damage of carbon fiber bundles when rubbing against different metal materials, which indicates that the friction damage between the heddle eyes and the carbon fiber bundle was reduced after copper plating. |
