摘　　要：展纤能够使碳纤维丝束厚度变薄、幅宽变宽,明显改善后道应用中预制件的力学性能。阐述了大丝束碳纤维的概念、特点及展纤目的,介绍了大丝束碳纤维展开性表征方法,分析了展纤对大丝束纤维形态、纤维渗透性及复合材料性能的影响;归纳总结了多辊热碾展纤技术、机械式多辊筒展纤技术、声波辅助展纤技术、静电辅助展纤技术、微突起阵列辅助展纤技术和气流扰动展纤技术等6种展纤技术的研究现状。各种展纤技术各有利弊,气流扰动展纤技术是最具发展前景的展纤技术,未来应重视多种展纤技术相结合的应用研究,提升对大丝束碳纤维的展纤效果,降低展纤过程对碳纤维的损伤。Carbon fiber-reinforced composites have a series of advantages such as light weight,high strength and high modulus,corrosion resistance,strong designability,and easy integral molding,and are widely used in automobile manufacturing,aerospace,sports,energy,wind turbine blades,and so on.In the entire carbon fiber production chain,the cost of raw silk required for the production of small tow carbon fiber is more than four times the cost of raw silk required for the production of large tow carbon fiber,which somewhat restricts the wide application of carbon fibers.In order to expand the application of carbon fibers,large tow carbon fibers with lower cost can be chosen.In the application of large tow carbon fibers,it is necessary to spread the fibers to improve the wettability of the resin to the carbon fiber tows.The exploration of spreading fiber technology began in the 1970 s,but the initial research on this technology was still relatively simple and slowly evolved into a diversified development trend by the end of the 1990 s.Entering the 21 st century,the carbon fiber production technology has gradually improved,and the spreading technology for tow carbon fibers tends to be increasingly mature.Fiber spreading technology helps large tow carbon fibers maximize the advantages of small tow carbon fibers,fully exerts the reinforcing effect of large-tow carbon fibers,and achieves high efficiency and low cost in the preparation of composite materials.Thus,the spreading technology of large tow carbon fibers is crucial in the preparation and application of composite materials reinforced by carbon fibers.The spreadability of carbon fiber tows can be measured by the change in width of carbon fiber tow before and after spreading.The spreading effect affects the morphology of carbon fiber tow,permeability and structural properties of composites.The commonly used fiber spreading technologies for large tow carbon fibers mainly includes the following six types:multi-roller thermal rolling spreading method,mechanical multi-roller s
