摘　　要：制备了表面接枝了聚酰胺链段的炭纤维/PSF-MC尼龙6复合材料,接枝率为1.3%。DSC研究表明,与MC尼龙6相比,接枝后的炭纤维/PSF-MC尼龙6复合材料中基体尼龙6的起始结晶温度和最大结晶温度均有所提高,α型晶体和γ型晶体均增多。力学性能测试和扫描电镜观察实验结果都表明在炭纤维表面接枝聚酰胺链段后,炭纤维与基体尼龙6的界面粘接性和相容性得到提高,力学性能测试表明,聚砜的加入提高了复合材料的弯曲强度。The functional group of-TDI-PL was grafted on the surface of carbon fiber and the grafting ratio is about 1.3%, then CF/PSF-MC nylon 6 in-situ composite was prepared successfully. Differential scanning calorimetry （DSC） research result indicates that： compared with MC nylon 6, both the beginning crystallization temperature and the max crystallization temperature of nylon 6 in carbon fiber without grafting/PSF-MC nylon 6 insitu composite are higher, and its a crystal reduces, but its T crystal increases; both the beginning crystallization temperature and the max crystallization temperature of nylon 6 in carbon fiber with grafting/PSF-MC nylon 6 in-situ composite is higher, and both its a crystal and T crystal increase. Mechanical property test and scanning electron microscope（SEM） indicate that it betters the interracial cohesion and consistence between carbon fiber and nylon 6 to graft polyamide chain on the surface of carbon fiber. Mechanical property test indicates that polysulphone enhances the bending strength of composites.
