标准摘要
[中文适用范围]： 该文献描述了一种脉冲传播方法，用于确定聚合物在离散频率（通常在 3 kHz 至 10 kHz 范围内）下的复数拉伸模量 E' 的存储分量。 该方法适用于测量储能模量在 0.01 GPa 至 200 GPa 范围内且损耗因数在 10 kHz 左右低于 0.1 的材料。 对于具有较高损耗的材料，速度测量中的显着误差会通过振幅衰减而引入。 该方法允许在薄膜或细纤维和长样本上进行测量，通常是 300 mm × 5 mm × 0,1 mm 的带材或 300 mm × 0,1 mm（直径）的纤维。 该方法可能不适用于泡沫塑料、复合塑料和多层产品。 [外文原描述]： This document describes a pulse propagation method for determining the storage component of the complex tensile modulus E ' of polymers at discrete frequencies typically in the range 3 kHz to 10 kHz. The method is suitable for measuring materials with storage moduli in the range 0,01 GPa to 200 GPa and with loss factors below 0,1 at around 10 kHz. With materials having a higher loss, significant errors in velocity measurement are introduced through decay of amplitude. The method allows measurements to be made on thin films or fine fibres and long specimens, typically tapes of 300 mm × 5 mm × 0,1 mm or fibres of 300 mm × 0,1 mm (diameter). This method may not be suitable for cellular plastics, composite plastics and multilayer products.
