Research Development of Interlaminar Reinforcing and Toughening Technique of Carbon Fiber Composites

碳纤维树脂基复合材料增韧技术的升级是先进复合材料高性能化的重要途径,已经从应用于第2代复合材料的热塑性塑料共混增韧树脂基体,发展成为第3代复合材料中的层间增强增韧技术。北京化工大学先进复合材料研究中心(Advanced Composites Center,ACC)针对复合材料层间增韧技术,分别开展纳米纤维、胶膜和颗粒3种方法的基础研究,突破了方法构建和增韧机理等科学问题,并实现了颗粒层间增韧方法的工程应用。总结了ACC团队在层间增强增韧方向的研究成果,结合国内外研究进展,对比了3种层间增韧技术及其多尺度增强增韧的效果,并展望了层间增韧技术的发展及应用前景。

The upgraded toughening technique of carbon fiber reinforced polymer was the important approach for preparing high performance composites.In the second-generation composite,thermoplastics have been used to toughen resin matrix by physical blending.In the third-generation composite,interlaminar reinforcing and toughening methods have been developed.Fundamental researches on nanofibers,resin films and particles interlaminar toughening carbon fiber composites have been carried out by Advanced Composites Center(ACC)in Beijing University of Chemical Technology(BUCT),and the scientific problems of method constriction and toughening mechanism were broken through and the engineering application of particle interlaminar toughening was also achieved.Combining with domestic and foreign developments,the accomplishments of ACC teams in interlaminar reinforcing and toughening were reviewed,and the effects of three kinds of interlaminar toughening and corresponding multiscale interlaminar reinforcing and toughening techniques were contrasted.And the application prospect on interlaminar reinforcing and toughening technique was expected.
