Abstract

As the mechanical performance of 3D printed polymers advances, there arises an urgent demand for enhanced methodologies to ensure their structural integrity. In this work, magnetostrictive polymer composites (MPCs) are investigated utilizing an ultraviolet (UV) curable epoxy resin through direct ink writing (DIW) for internal stress detection. A strong correlation between stress and magnetic flux change was observed within the printed MPCs. Impact from the inclusion of fumed silica (FS) as a rheological filler in the matrix were identified and investigated. The tensile strengths of the MPCs were in the range of 31 MPa–34 MPa. The changes in magnetic flux density (ΔB) of the MPCs under quasistatic loading were within the interval of 0.5 to 5.4 Gauss. A similar sensing behavior was obtained for the MPCs during cyclic loading. A similar sensing behavior was obtained for the MPCs during cyclic loading. Furthermore, it was found that incorporating the MPCs into specific layers further increased the tensile strength to over 40 MPa while still showing a significant ΔB response. Additionally, localized deposition of magnetostrictive particles at known stress concentrations emerged as a promising strategy for future stress-sensing endeavors.

用于无线应力传感的 3D 打印磁致伸缩聚合物复合材料 (MPC)

随着三维打印聚合物机械性能的不断提高，迫切需要增强的方法来确保其结构的完整性。在这项工作中，研究人员利用紫外线（UV）固化环氧树脂，通过直接墨水写入（DIW）技术对磁致伸缩聚合物复合材料（MPC）进行了内部应力检测。在印刷的 MPC 中观察到了应力与磁通量变化之间的密切联系。在基体中加入气相二氧化硅（FS）作为流变填料所产生的影响得到了确认和研究。MPC 的拉伸强度在 31 兆帕-34 兆帕之间。在准静态加载条件下，MPC 的磁通密度 (ΔB)变化范围在 0.5 至 5.4 高斯之间。在循环加载过程中，MPC 也有类似的感应行为。在循环加载期间，MPC 也获得了类似的传感性能。此外，研究还发现，在特定层中加入 MPC 可进一步提高拉伸强度，使其超过 40 兆帕，同时仍显示出显著的 ΔB 响应。此外，在已知的应力集中位置局部沉积磁致伸缩颗粒也是未来应力传感工作的一种有前途的策略。
