Abstract: In order to study the feasibility and mechanics properties of the aluminum alloy/carbon fiber prepreg laminates by rolling processes, they were prepared based on different surface treatments of the aluminum sheets and rolling reductions, the effects of the surface treatment processes and reduction on the flexural mechanics properties of the laminates were analyzed by the three point bending tests. The results show that the surface treatment processes and the reductions have significant influences on the mechanics properties of the laminates. The bending performance of the laminatesis improved significantly by the anodizing processes, the flexural strength is as 573 MPa and the modulus is as 80.9 GPa, compared with the surface untreated samples they increase by 65.9% and 39.1% respectively, the interfacial bonding performance is obviously better than that of chemical cleaning and mechanical grinding processes. The failure mode of the laminates transformed the fiber integral fracture and the lamination into the fiber buckling deformation. When the reduction isas 6.5%, the interface of the aluminum alloy/fiber resin is neat and smooth, and the flexural performance of the laminates is optimal, It is indicated that the appropriate rolling pressure is beneficial to the resin flow infiltrating fiber, compacting interlayer porosity, and conducive to form a stable mechanical occlusal structure on the surface of the resin and aluminum alloy.

摘要： 为研究铝合金/碳纤维预浸料轧制制备层板的可行性及力学性能，基于铝板不同表面处理工艺和轧制压下量，制备了碳纤维增强铝合金层板。结合三点弯曲试验分析了表面处理工艺和压下量对层板弯曲力学性能的影响。结果表明：铝合金表面处理工艺和轧制压下量对层板力学性能影响显著，经阳极氧化工艺处理后所得层板弯曲性能改善最为明显，弯曲强度和模量分别为573  MPa和80.9 GPa,相比表面未处理试样分别增加了65.9%和39.1%，界面结合性能明显优于化学清洗法和机械打磨法，层板破坏形式由纤维整体断裂和分层失效转变为纤维屈曲变形;当压下量为6.5%时，铝合金/纤维树脂界面整洁平齐，层板弯曲性能最优，表明适当的轧制压力有利于树脂流动浸润纤维，压实层间孔隙，促进树脂与铝合金表面形成稳定的机械咬合结构。
