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.
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).
