Abstract

Double-curved composite components are widely used in aerospace and transportation due to their high specific strength and low wind drag. However, wrinkling is a main defect induced during the double-curved forming of quasi-isotropic composite preforms. This study aims to numerically investigate the strategies for suppressing wrinkles during the double-curved forming process with the aid of separators. A quantitative assessment of wrinkles was achieved by point-cloud analysis. The simulation results reveal that the severity of wrinkle defects exhibits a strong correlation with separator thickness and fabric-tool friction coefficient, while showing little dependence on the fabric-fabric friction coefficient. The investigation also demonstrates that wrinkle formation is primarily attributed to the work of friction, rather than the frictional force itself. Finally, considering the balance between cost and forming quality, a separator thickness of 4 mm and a fabric-separator friction coefficient of 0.3 were identified as the optimal configuration.

双弯曲成形中减少起皱：带分离器的准各向同性预制件数值研究

双弯复合材料构件具有高比强度、低风阻等特点，广泛应用于航空航天和交通运输领域。然而，起皱是准各向同性复合材料预制件双弯曲成形过程中产生的主要缺陷。本研究旨在数值研究在双曲成形过程中利用分离器抑制起皱的策略。通过点云分析实现了皱纹的定量评估。仿真结果表明，起皱缺陷的严重程度与分离器厚度和织物-工具摩擦系数有较强的相关性，而与织物-织物摩擦系数的相关性较小。调查还表明，皱纹的形成主要归因于摩擦的工作，而不是摩擦力本身。最后，考虑成本与成型质量的平衡，确定了隔膜厚度为4 mm、织物-隔膜摩擦系数为0.3的最优配置。

期刊介绍： Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
