Abstract

Based on the research of Polyvinyl alcohol (PVA)/Waterborne Polyurethane (WPU)/Short Carbon Fibers (SCFs) novel electrochemically shape memory composites, this study delved into an exploration of factors influencing the shape memory deformation of shape memory film samples when subjected to voltage stimulation. These main affecting factors encompassed sample thickness, activation voltage, and wire layout. Subsequently, based on the above conclusions, the viscoelastic constitutive model of PVA/WPU/SCFs composite was established based on Maxwell model and the deformation deflection of the composite film was predicted by shape memory recovery, and the electrothermal coupling simulation analysis and shape memory recovery and deformation simulation verification were carried out. Finally, based on the shape memory recovery performance of the composite film, a new reciprocating moving deformation structure was conceptualized, characterized by distinct cycles of motion, each analyzed individually.

基于 PVA/WPU/SCF 的复合薄膜的电驱动形状记忆形变控制与验证

本研究以聚乙烯醇（PVA）/水性聚氨酯（WPU）/短碳纤维（SCFs）新型电化学形状记忆复合材料的研究为基础，深入探讨了影响形状记忆膜样品在电压刺激下的形状记忆变形的因素。这些主要影响因素包括样品厚度、激活电压和导线布局。随后，在上述结论的基础上，基于麦克斯韦模型建立了 PVA/WPU/SCFs 复合材料的粘弹性构成模型，并通过形状记忆恢复预测了复合薄膜的变形挠度，进行了电热耦合仿真分析和形状记忆恢复及变形仿真验证。最后，根据复合薄膜的形状记忆恢复性能，构思了一种新的往复运动变形结构，其特点是运动周期不同，每个周期单独分析。

期刊介绍： The Journal of Reinforced Plastics and Composites is a fully peer-reviewed international journal that publishes original research and review articles on a broad range of today''s reinforced plastics and composites including areas in: Constituent materials: matrix materials, reinforcements and coatings. Properties and performance: The results of testing, predictive models, and in-service evaluation of a wide range of materials are published, providing the reader with extensive properties data for reference. Analysis and design: Frequency reports on these subjects inform the reader of analytical techniques, design processes and the many design options available in materials composition. Processing and fabrication: There is increased interest among materials engineers in cost-effective processing. Applications: Reports on new materials R&D are often related to the service requirements of specific application areas, such as automotive, marine, construction and aviation. Reports on special topics are regularly included such as recycling, environmental effects, novel materials, computer-aided design, predictive modelling, and "smart" composite materials. "The articles in the Journal of Reinforced Plastics and Products are must reading for engineers in industry and for researchers working on leading edge problems" Professor Emeritus Stephen W Tsai National Sun Yat-sen University, Taiwan This journal is a member of the Committee on Publication Ethics (COPE).
