摘要

本文讨论了胶粘剂的粘弹性材料特性对结构健康监测(SHM)传感器功能的影响。胶粘剂表现为粘弹性，其机械性能表现出强烈的温度和时间依赖性。蠕变过程增加了黏合剂(聚合物)在机械载荷作用下的变形，而松弛过程可以随时间减小黏合剂(聚合物)的应力。这些过程在玻璃化转变(Tg)温度范围内最为有效，在此温度范围内，材料的行为在玻璃态和橡胶态之间切换，所有材料参数都发生了巨大变化。此外，粘弹性材料的性能受到环境载荷的影响，如湿度，因为它的行为就像环氧树脂基体中的增塑剂。

Measurement of viscoelastic material properties of adhesives for SHM sensors under harsh environmental conditions

This paper addresses the influence of the viscoelastic material properties of adhesives on the functionality of SHM (Structural Health Monitoring) sensor applications. Adhesives behave viscoelastically and show a strong temperature and time dependency of their mechanical properties. Creep processes increase the deformation under mechanical load and relaxation can decrease the stress in the adhesives (polymer) with time. These processes are most effective in the temperature range of glass transition (Tg), at which the material behavior switches between the glassy and rubbery state and all material parameters change drastically. Additional the viscoelastic material properties are influenced by environmental loading like moisture as it behaves like a plasticizer in the epoxy matrix.
