由于橡胶材料用于减振，弄清损耗因子与微观结构之间的关系将有助于开发高性能的减振材料。虽然利用X射线计算机层析成像(CT)在重复变形下进行无损观测已有报道，但尚未有亚微米量级的观测到低应变变形，如振动暴露。具有不同损耗因子的材料的内部变形行为尚未得到评估。本研究提出了一种拉伸幅值下试件的动态X射线CT方法，直接评估材料在动态条件下的内部变形行为。所提出的四维CT的激励频率为1μ，空间分辨率为0.5兆赫兹。通过X射线CT获得各阶段的局部应变，并对其变形行为进行了评估。结果表明，随着细小颗粒的掺入，局部应变幅值分布曲线的峰值降低，分布变宽。
As rubber materials are used for damping, clarifying the relationship between the loss factor and microstructure would help develop high-performance damping materials. Although nondestructive observations using X-ray computed tomography (CT) under repetitive deformation have been reported, no observations have been reported at the submicron order that capture low-strain deformation, such as vibration exposure. The internal deformation behavior of materials with different loss factors has not yet been evaluated. This study proposes a dynamic X-ray CT method for specimens under tensile amplitudes, directly evaluating the internal deformation behavior of materials under dynamic conditions. The proposed 4D-CT has an excitation of 1 Hz and a spatial resolution of 0.5 μm. The local strain was obtained from X-ray CT at each phase, and the deformation behavior was evaluated. The results revealed that the peak of the local strain amplitude distribution curve decreased and the distribution widened as fine particles were mixed.
