摘要整理
本研究采用真空辅助树脂传递模塑（VARTM）工艺，研究了等离子体处理对碳纤维润湿性的影响，并系统调查了等离子体处理对碳纤维增强复合材料（CFRP）力学性能的影响，包括层间剪切强度和拉伸性能。通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和X射线光电子能谱（XPS）对碳纤维表面化学成分进行了分析。结果表明，低温等离子体处理对碳纤维表面形貌影响较小，但改变了碳纤维的化学表面状态，显著增强了碳纤维的润湿性，树脂浸润速度提高了2倍以上。纤维润湿性的改善对VARTM工艺制备CFRP复合材料具有重要意义。与未处理碳纤维相比，等离子体处理导致CFRP复合材料拉伸性能有可接受的下降，但层间剪切强度显著提高。低温等离子体处理在CFRP复合材料的有效制备和应用中发挥了重要作用。
