Abstract

This study explores how expanded thermoplastic polyurethane (ETPU) responds to temperature and compression at various temperatures. Dynamic mechanical thermal analysis (DMTA) was used to understand the temperature influence at small deformations. To investigate the deformation behavior at different compression stages we employed in-situ CT measurements and 3D strain mapping. Through quasi-static compression tests at temperatures from − 50 to 120 °C, we determined the influence of temperature on compression modulus, elastic stress, stress at 50% deformation, densification, and energy absorption. Remarkably, ETPU demonstrates robust recovery after compression, particularly within the − 50 to 60 °C temperature range. Subsequent compression tests show consistent or even slightly increased compression properties, such as a 10% increase in energy absorption for samples previously tested at − 40 °C, indicating that ETPU can withstand prior exposure to different temperatures.

温度对发泡热塑性聚氨酯（ETPU）压缩性能的影响

本研究探讨了发泡热塑性聚氨酯（ETPU）在不同温度下对温度和压缩的反应。我们使用动态机械热分析（DMTA）来了解小变形时的温度影响。为了研究不同压缩阶段的变形行为，我们采用了原位 CT 测量和三维应变绘图。通过在 - 50 至 120 °C 温度范围内进行准静态压缩试验，我们确定了温度对压缩模量、弹性应力、50% 变形时的应力、致密化和能量吸收的影响。值得注意的是，ETPU 在压缩后表现出强劲的恢复能力，尤其是在 - 50 至 60 °C 的温度范围内。随后的压缩测试表明，ETPU 的压缩性能保持一致，甚至略有提高，例如之前在 - 40 °C 下测试的样品的能量吸收率提高了 10%，这表明 ETPU 可以承受之前暴露在不同温度下的情况。
