标准摘要
[中文适用范围]： 该文献描述了一种强制非共振方法，用于确定聚合物在频率通常在 0.01 Hz 至 100 Hz 范围内的拉伸复数模量 E* 的分量。 注：可以进行更高频率的测量，但可能会导致测量的动态特性出现重大误差（见 10.2.2 和 10.2.3）。 该方法适用于测量 0.01 GPa 至 5 GPa 范围内的动态储能模量。 尽管可以研究模量超出此范围的材料，但为了获得更高的精度，可使用替代变形模式 [即 G' < 0,01 GPa 的剪切模式（参见 ISO 6721-6）和 E' 的弯曲模式> 5 GPa（参见 ISO 6721-3 或 ISO 6721-5）]。 该方法特别适合测量损耗因数，因此可以方便地用于研究大部分玻璃橡胶松弛区域的动态特性随温度和频率的变化（参见 ISO 6721-1）。 在较宽的频率和温度范围内确定的数据的可用性使得能够使用频率-温度变换程序导出主图，该程序显示不同温度下扩展频率范围内的动态特性。 [外文原描述]： This document describes a forced, non-resonance method for determining the components of the tensile complex modulus E* of polymers at frequencies typically in the range 0,01 Hz to 100 Hz. NOTE Higher frequency measurements can be made, but significant errors in the dynamic properties measured are likely to result (see 10.2.2 and 10.2.3). The method is suitable for measuring dynamic storage moduli in the range 0,01 GPa to 5 GPa. Although materials with moduli outside this range can be studied, alternative modes of deformation are intended to be used for higher accuracy [i.e. a shear mode for G′ < 0,01 GPa (see ISO 6721-6) and a flexural mode for E′ > 5 GPa (see ISO 6721-3 or ISO 6721-5)]. This method is particularly suited to the measurement of loss factors and can therefore be conveniently used to study the variation of dynamic properties with temperature and frequency through most of the glass-rubber relaxation region (see ISO 6721-1). The availability of data determined over wide ranges of both frequency and temperature enables master plots to be derived, using frequency-temperature shift procedures, which display dynamic properties over an extended frequency range at different temperatures.
