摘要
复合材料自动铺丝(Automated fiber placement,AFP)技术是一种低成本、高性能的先进复合材料自动化制造技术。为充分利用预浸料铺放变形及黏合特性来改善铺放质量,从预浸料丝束变形–黏合行为与工艺参数的关联机制和典型工艺缺陷对构件力学行为影响机理两个方面对国内外研究现状进行综述,分析了工艺参数与工艺缺陷对复合材料铺丝构件力学行为的影响机制;最后,提出了与复合材料铺丝构件力学行为相关的研究内容和科学问题。
The automated fiber placement(AFP)technology is gaining importance in advanced manufacturing of low-cost and high-performance composites.In order to improve the layup quality based on the compression response and tackiness of prepregs,this paper reviews recent development on the deformation and bonding mechanisms of uncured prepregs over a wide range of processing conditions as well as the AFP process induced defects and effects on mechanical behavior of composites at home and abroad.The research efforts in the future are probably going to focus on the development and related scientific problems of the mechanical behavior of AFP-related composites.
