摘　　要：碳纤维复合材料是通过双螺杆反应挤出机复合制备,研究了复合材料的微结构和力学性能,碳纤维的扫描电镜照片显示,处理后的碳纤维较未处理碳纤维有更好的表面粗糙度。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50%。Carbon fiber-reinforced composites （CFRP） were prepared successfully by twin-screw extruder. Microstructure and mechanical properties of CFRP were studied. Scanning electron microscope （SEM） photograph of carbon fiber（CF） treated by nitric acid indicated more legible grooves than that of untreated one. It shows good matrix-carbon fiber adhesion between the treated CF with fracture surface morphology and PA6. The mechanical property of composite is enhanced compared with pure PA6. Especially, tensile strength and tensile modulus are enhanced by 33% and by 50% respectively.
