绪 言 振簧式动态粘弹谱仪用于测量聚合物及其复合材料的动态力学性能。 动态力学性能是指材料在变化应力作用下的力学行为。动态力学性能的测试,可以同时得到材料的动态弹性模量和力学损耗数据。 聚合物是十分典型的“粘弹性”材料。当它受力变形时,部分能量转换成位能贮存起来,另一部分则转换成热能而损耗掉。后者被称之为“力学损耗”或“力学阻尼”。 动态力学试验是一个相当新的领域,但是无论从实用或科学的观点而言,它都已成为用 Introduction The spring-loaded dynamic viscoelastic spectrometer is used to measure the dynamic mechanical properties of polymers and their composites. Dynamic mechanical properties refers to the mechanical behavior of materials under varying stress. Dynamic mechanical properties of the test, you can get the dynamic modulus of elasticity and mechanical loss data. Polymers are very typical “viscoelastic” materials. When it is deformed by force, some of the energy is converted into bits and stored, while the other part is converted into heat and lost. The latter is called “mechanical loss” or “mechanical damping.” Dynamic mechanical testing is a fairly new field, but it has become an attractive tool both in practical and scientific terms
