摘　　要：纤维增强复合材料由于其优良性能,在航空领域有了越来越广泛的应用。但是复杂曲面铺层的区域划分以及剪口处理技术、铺层曲面的展开技术、数控下料技术等关键技术尚未得到很好解决,因此复合材料设计制造的数字化程度不高。本文主要针对复合材料制造过程中的复杂曲面展开问题进行了相关的研究工作,根据复合材料铺层时的变形特点提出了一种可用的双基线铺层展开方法。Fiber reinforced composite materials due to its excellent performance, a more widely used in the field of a- viation, but the complex surface overlay area dividing notches processing technology, paved the layer surfaces expand tech- nology, CNC cutting technology and other key technologies have not been satisfactorily solved, so the design and manufac- ture of the composite material is not high degree of digitization. In this paper, for the complex surface＇ s spreading problem of the composite materials manufacturing process, We have carried out the related research work, depended on the deform- ation characteristics of composite overlay, We have proposedan available dual baseline overlay and spreading algorithm.
