摘　　要：为制备低碳纤维含量的耐磨复合材料,使用3D打印技术结构可设计的优势对纤维排列进行调控,从而影响碳纤维增强环氧树脂基复合材料的摩擦磨损性能。成功制备堆叠和仿生螺旋结构的3D打印复合材料,探究复合材料的硬度、导热系数、摩擦磨损性能与打印结构的关系。结果表明,由于纤维排列方式及层间应力传递效率不同,0°堆叠结构和仿生螺旋结构的样品显示出最低磨损率,分别为1.272×10^(-4)mm^(3)/(N·m)和1.283×10^(-4)mm^(3)/(N·m),获得了低碳纤维含量下耐磨性能优异的短切碳纤维增强树脂复合材料。研究成果展示了3D打印仿生螺旋结构复合材料在摩擦磨损领域的显著优势。In order to prepare wear-resistant composites with low carbon fibre content,the fibre arrangement was modulated using the advantage of the structural designability of 3D printing technology,which affects the friction and wear properties of carbon fibre reinforced epoxy resin matrix composites.3D printed composites with stacked and Bouligand structure were successfully prepared,while the relationships between the hardness,thermal conductivity,and friction and wear properties of the composites and the printed structures were investigated.The results show that due to the different fiber arrangements and interlayer stress transfer efficiency,the samples with 0°stacked structure and Bouligand structure show the lowest wear rates of 1.272×10^(-4)mm^(3)/(N·m)and 1.283×10^(-4) mm^(3)/(N·m)respectively,and excellent wear-resistant short-cut carbon fibre-reinforced resin at a low carbon fibre(5.7 wt%)con-tent were obtained composites.The research results show the significant advantages of 3D printed Bouligand structure composites in the field of friction and wear.
