【摘要】 通过对不同结构预浸带的对比研究，得出了具有良好表面状态单向预浸带所具有的结构，并且从微观上研究了纤维与树脂的结合方式，得出了影响其表面状态的原因。通过对树脂体系的改进，使纤维能够处于树脂体系的交联结构之中，提高了横向撕裂强度，从而改进了单向预浸带的表面状态。更多还原

【Abstract】 The structure of the unidirectional carbon fiber prepreg tape with good surface state was obtained by means of the study on prepreg tape with different structures .The miroscopic combination mode of fibers and resin was studied and the influencing aspects of surface state of the prepreg tape were analyzed.The resin system was improved to make the fiber be in the cross-link structure of the resin ,so that the transversetear strength and the surface state of unidirectionol carbon fiber prepreg tape were improved .更多还原
