摘要
连续纤维增强热塑性复合材料由于优异的力学和化学性能,具有广阔的应用前景.针对高性能复杂结构零件自动化制造需求,以自动铺放及连续纤维3D打印成型技术为代表的连续纤维增强热塑性复合材料的增材制造技术引起广泛关注.增材制造过程是一个包含多尺度、多物理场的复杂过程,工艺机制尚不明确,且热塑性聚合物具有熔点高、黏度大等特性,增大了加工难度,成型工艺控制极具挑战.由于成型过程包含一系列力学问题,采用多尺度工艺力学仿真,结合理论与实验研究可以构建成型工艺参数及成型工艺质量之间的关联,为优化工艺参数设计和装备模块设计提供理论支持.多尺度模拟工艺力学及机制研究涉及到对各类复杂物理现象的理解和捕捉,算法种类繁杂,模型构建难度大,使得多尺度工艺力学建模颇具挑战性.本文总结了近年来不同尺度模拟方法在自动铺放及连续纤维3D打印等连续纤维增强热塑性复合材料工艺机制研究方面的进展,并对未来的发展方向及应用前景进行了分析和展望.
Abstract
Continuous fiber-reinforced thermoplastic composites offer exceptional mechanical and chemical pro-perties,attracting widespread attention in both academia and industry.To meet the automation requirements for high-performance complex structural components,additive manufacturing technologies for continuous fiber-rein-forced thermoplastic composites have garnered significant interest.These manufacturing methods include Fused Deposition Modeling and automated fiber placement.The additive manufacturing process involves multi-scale physical phenomena,presenting a complex interplay that is not yet fully understood.The inherent properties of thermoplastic polymers,such as their high melting points and viscosities,further complicate processing,posing substantial challenges in the control of manufacturing processes.Addressing the intricate mechanical challenges within the manufacturing process can be facilitated through the application of multi-scale process mechanics simulations.The integration of these simulations with theoretical and empirical research aids in forging a clear cor-relation between manufacturing process parameters and the quality of the final product.This provides theoretical support for optimizing process parameters and equipment module design.However,the implementation of multi-scale process simulation requires in-depth comprehension and precise description of physical phenomena.It also involves the design of sophisticated algorithms and the construction of intricate models,thereby increasing the difficulty and challenge of the simulation.This paper reviews recent studies employing various numerical modeling approaches to investigate the processing mechanisms of continuous fiber reinforced thermoplastic composites during the AFP and FDM processes.It also outlines potential promising directions in the field.
