摘　　要：连续纤维增强复合材料因其优异的比刚度、比强度等特性,在航空航天、国防军工、医疗器件等高端装备领域得到了广泛的关注和应用。其中,纤维方向对连续纤维增强复合材料的力学性能有着重要影响,但是由于常规制造工艺的局限,纤维路径通常沿0°、45°、90°等规律一致的方向来设定,连续纤维增强复合材料的优势无法被充分利用。如今,3D打印技术促进了制造具有复杂曲线纤维路径复合材料的发展,其对应的纤维方向及路径优化设计方法正逐步引起国内外专家学者的重点关注。本文围绕纤维增强复合材料的纤维方向及路径优化设计方法,介绍了正交各向异性材料方向优化理论,回顾了纤维角度优化方法,总结了现有纤维路径规划算法,探讨了相关前沿问题并做出了未来展望。本文为高性能连续纤维增强复合材料的优化设计和制造提供了重要信息,有助于推动高性能连续纤维增强复合材料的快速发展和广泛应用。Continuous fiber reinforced composites have gained wide attention and application in high-end equipment fields such as aerospace,defense,and medical devices,due to their excellent specific stiffness,specific strength,and other properties.The fiber orientation has a significant impact on the mechanical performance of continuous fiber reinforced composites.However,due to the limitations of conventional manufacturing processes,the fiber paths are usually set along regular directions such as 0°,45°,90°,etc.,which hinders the full utilization of the advantages of continuous fiber reinforced composites.Nowadays,the development of 3D printing technology has facilitated the manufacturing of composites with complex curved fiber paths,and the corresponding optimization methods for fiber orientation and path design have gradually attracted attention from experts and scholars worldwide.In this article,we focus on the optimization methods for fiber orientation and path design of fiber reinforced composites.We introduce the theory of orthogonal anisotropic material direction optimization,review the methods for fiber angle optimization,summarize the existing fiber path planning algorithms,discuss relevant cutting-edge issues,and provide future prospects.This review provides important information for the design optimization and manufacturing of high-performance continuous fiber reinforced composites,which will contribute to the rapid development and wide application of continuous fiber reinforced composites.
