摘 要: 通过双螺杆挤出机对碳纤维和尼龙6进行复合制备,研究了碳纤维增强聚合物基复合材料(carbon fiber-reinforced plastics, CFRP)的界面结构和力学性能,通过碳纤维的扫描电镜照片发现:硝酸处理的碳纤维较未处理的碳纤维表面有更高的表面粗糙度。复合材料断面照片显示:处理后的碳纤维和基体尼龙6材料有着很好的界面结合。复合材料的力学性能得到提高,其拉伸强度和拉伸模量分别提高了33%和55%. 示差扫描量热法(differential scanning calorimetry,DSC)测试显示:碳纤维在复合材料中起到了异相成核作用。
关 键 词: 有机高分子材料;碳纤维;硝酸氧化;界面结合;双螺杆挤出

Abstract: Carbon fiber-reinforced composites were prepared successfully by twin-screw extruder. Microstructure and mechanical properties of carbon fiber-reinforced plastics (CFRP) were studied. Scanning electron microscope photograph of carbon fiber treated by nitric acid indicated more legible grooves than that of untreated one. It shows good matrix-carbon fiber adhesion between the treated carbon fiber (CF) with fracture surface morphology and polymide 6 (PA6). The mechanical property of composite is enhanced compared with pure PA6. Especially, tensile strength and tensile modulus are enhanced by 33% and 50% respectively. Differential scanning calorimetry (DSC) curves of sample illustrate CF plays a part of heterogeneous nucleation in composite.
Key words: functional organic polymer material; carbon fiber; nitric acid oxidation; interfacial adhesion; twin-screw extruder
