摘　　要：基于"离位"增韧技术,将"离位"增韧剂聚醚砜均匀地附载在增强织物上,制备具有增韧功能的ES-Fabric增强织物。以ES-Fabric增强织物作为增强体,采用垂直流动RTM工艺制备了"离位"增韧的不同树脂基(6421、3266和5284树脂)复合材料,并进行了性能研究,结果表明:垂直流动RTM工艺缩短了注胶时间,改善了"离位"增韧的RTM工艺,"离位"增韧的复合材料不仅提高了复合材料层压板的冲击损伤阻抗(用分层的投影面积超声C扫描来评价),也提高了层压板的冲击后压缩强度(用CAI值来评价),并且增韧后的复合材料的基本力学性能并没有降低。The ES-fabric reinforced fabrics with toughening function were prepared by adhering the ex-situ elasticizer polyethersulphone homogeneously on reinforced fabrics according to ex-situ toughened technology.Different resin（6421,3266 and 5284resin）matrix composites based on ex-situ toughening concept were prepared by RTM process taking ES-fabric reinforced fabrics as reinforcement.And the mechanical properties were compared with un-toughened composites.The results showed that vertical flow of RTM process had shortened resin injection time and improved RTM process for Ex-situ toughening.Composites based on ex-situ toughening concept not only improved impact damage resistance（appraised by the shadow area of delamination C-scan）,also improved compression after impact（appraised by CAI value）.The mechanical properties of toughened composites had no reduction.
