摘　　要：纤维增强树脂基复合材料具有比模量比强度高、耐冲击、抗蠕变、抗震等特点,在航空、汽车、海洋工业中得到广泛的应用。纤维铺放作为先进复合材料成型技术之一,能够高效率、高质量、高重复性和低成本加工大曲率复合材料零件。橡胶压辊在压力作用下会产生变形,从而增加压辊与基底接触的面积,并进一步改善层间结合度。由于不同铺放压力会导致压辊产生不同的变形量,针对纤维铺放压辊变形过程进行分析,通过建立压辊压应力分布模型,获得接触压应力、压辊下压量以及压辊与基底的变形接触区域之间的映射关系,并通过实验验证了该模型的有效性。The fiber reinforced resin-based composite materials have the characteristics of high specific modulus and strength,impact resistance,creep resistance,and seismic resistance,which are widely used in the aviation,automotive,and marine industries.As one of the advanced composite material forming technologies,the fiber placement can manufacture the large-curvature composite parts with the high efficiency,high quality,high repeatability and low cost.The rubber compaction roller will deform under the pressure,in which the deformation will increase the contact area between the pressure roller and the substrate,and improve the interlaminar bonding degree.Due to the different deformation of the compaction roller caused by the different laying pressures,the deformation process of the fiber compaction roller was analyzed.By establishing the pressure stress distribution model for the compaction roller,the contact pressure,the downward deformation of the compaction roller and the deformation contact area between the compaction roller and the substrate are obtained.The mapping relationship among the contact curves of the substrate is verified by using the experiments.
