标准摘要
[中文适用范围]： 本文件规定了一种基于共振曲线的弯曲振动法，用于测定均质塑料的 flexural 复数模量 E′f* 以及层压塑料的阻尼特性，例如由金属板和具有阻尼塑料涂层组成的系统或夹芯系统。对于许多应用来说，确定这些性质作为温度和频率的函数是有用的。 [外文原描述]： This document specifies a bending-vibration method based upon resonance curves for determining the flexural complex modulus E * f of homogeneous plastics and the damping properties of laminated plastics intended for acoustic insulation, for example systems consisting of a metal sheet coated with a damping plastic layer, or sandwich systems consisting of two sheet-metal layers with an intermediate plastic layer. For many purposes, it is useful to determine these properties as a function of temperature and frequency.
