本研究的目的是模拟形状记忆聚合物复合材料（SMPC）的形状固定性和时间依赖性部署，并评估纺织品的拉伸模量和弯曲模量对这些性能的影响。我们通过组合 SMP 层和增强层构建了 SMPC 模型。我们还考虑了 SMP 的热粘弹性以及增强层的拉伸模量和弯曲模量之间的值差异。利用该模型，我们模拟了纯弯曲条件下的部署。与实验结果的比较证实，我们提出的模型能够模拟 SMPC 中的形状固定性和时间依赖性部署。我们还证实，弯曲模量是形状固定性和随时间展开的重要因素，而拉伸模量与这些特性无关。
The purpose of the present study is to model shape fixity and time-dependent deployment in shape-memory polymer composites (SMPCs) and to evaluate the effect of textiles’ tensile and bending moduli on these properties. We constructed an SMPC model by combining SMP layers and a reinforcing layer. We also considered the thermo-viscoelasticity of SMP and the difference in values between the tensile and bending moduli of the reinforcing layer. Employing this model, we simulated deployment under pure bending conditions. Comparison with experimental results confirmed that our proposed model is able to simulate shape fixity and time-dependent deployment in SMPCs. We also confirmed that the bending modulus is an important factor for shape fixity and time-dependent deployment, whereas the tensile modulus has nothing to do with these properties.
