The measurement results reflect the material's response to alternating stress or strain. The viscoelasticity of the material. This document uses the DMA method to determine the storage modulus, loss modulus and loss factor of plastics as a function of temperature in non-resonant stretching mode. change. According to the above results, the glass transition, secondary relaxation, crystallization, cross-linking, phase separation, etc. of the plastic can be characterized. The above physical quantities determine the plastic Important parameters for using features.

Determination of dynamic mechanical properties of plastics Part 4.Non-resonant tensile vibration method1 ScopeThis document describes a forced non-resonant method for determining the tensile complex modulus E* of plastics in the frequency range 0.001Hz~100Hz. Note. Higher frequencies may lead to larger errors in the measured dynamic performance (see 9.5.1 and 10.1.2). This document is suitable for the determination of dynamic storage modulus between 0.01GPa and 5GPa, and can also be used to study plastics beyond this modulus range. However, its dynamic mechanical properties can be measured more accurately using other non-tensile deformation modes [i.e. shear mode with G' < 0.01GPa (see GB/T 33061.6), bending mode with E' >5GPa (see ISO 6721-3 or GB/T 33061.5)]. This document is particularly suitable for the determination of loss factors greater than 0.02, in order to facilitate the study of the dynamics of most glassy-rubbery relaxation zones. Can change with temperature and frequency (see GB/T 33061.1).2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text.
