The Novel Variable Stiffness Composite Systems with Characteristics of Repeatable High Load Bearing and Response Rate

The dataset was generated through the development and testing of a novel variable stiffness composite system (VSCS), which was created to address limitations in load capacity, response speed, and cycle work of traditional variable stiffness composites. The VSCS was prepared using a double-layer anisotropic structure, composed of a variable stiffness layer of polycaprolactone (PCL) and a driven layer of silicone elastomer with alcohol. The system demonstrated a continuous change in Young’s modulus from 0.1 to 7.263 MPa within 200 seconds and was capable of supporting a maximum weight 11.52 times its own weight. The dataset includes results from differential thermal analysis, thermogravimetric analysis, stiffness and strength analysis, heating/cooling efficiencies, volume expansion analysis, and load analysis. The materials were prepared using molds of specific dimensions, and various tests were conducted using equipment such as MTS universal tensile testers, DMA analyzers, and contact thermometers.

本数据集源于一款新型变刚度复合系统（variable stiffness composite system, VSCS）的研发与测试工作，该系统旨在弥补传统变刚度复合材料在负载能力、响应速度及循环做功方面的局限。该变刚度复合系统采用双层各向异性结构制备，由聚己内酯（polycaprolactone, PCL）制成的变刚度层与掺醇硅弹性体构成的驱动层组成。该系统可在200秒内实现杨氏模量从0.1 MPa至7.263 MPa的连续调控，且最大承重量可达自身重量的11.52倍。本数据集涵盖差热分析、热重分析、刚度与强度分析、升降温效率分析、体积膨胀分析以及负载分析的相关实验结果。实验所用材料通过特定尺寸的模具制备，各类测试则采用MTS万能拉伸试验机、动态机械分析（Dynamic Mechanical Analysis, DMA）分析仪及接触式温度计等设备完成。
