The result shows that cold plasma treatment improves the surface polarity of the carbon fiber, which enhances the impregnation of the carbon fiber braided by PET during the resin flowing process and improves the interfacial properties of RTM composites. ?

• 实验结果表明:冷等离子体处理可以使碳纤维表面活性提高,从而改善RTM工艺成型过程树脂对PET缝编碳纤维织物的浸润性,进而改善RTM成型复合材料的界面性能。
