摘要本文提出了一种不连续纤维复合材料制造过程的计算模型。这种新工艺的对准机制称为高性能不连续纤维(HiPerDiF)方法，涉及高度耦合的流固耦合作用。将长度在几毫米左右的纤维放入水悬浮液中，在两个平行板之间喷雾，然后沉积在移动的皮带上，制成一条排列整齐的不连续纤维带。这项技术可以作为复合材料回收过程的一部分，通过确保高水平的对准，将回收纤维再制造成有价值的回收复合材料原料。这项工作的目的是用光滑粒子流体力学对对准机构进行建模，以便为工业机械的设计提供参考。结果表明，喷射角和纤维长度对纤维排列的整体质量有影响。
ABSTRACT This work presents a computational model for a discontinuous fibre composite manufacturing process. The alignment mechanism of this novel process, called the High Performance Discontinuous Fibre (HiPerDiF) method, involves highly coupled fluid–structure interactions. Fibres with a length on the order of a few millimetres are placed in a water suspension, sprayed between two parallel plates and deposited on a moving belt to make an aligned discontinuous fibre tape. This technology can be used as part of a composites recycling process to remanufacture reclaimed fibres into valuable recycled composite feedstock by ensuring a high level of alignment. This work aims to model the alignment mechanism using smoothed particle hydrodynamics in order to inform the design of the industrial machine. The results reveal the influence of jet angle and fibre length on the overall quality of fibre alignment.
