动态力学热分析法测定合成薄膜的力学性能

Test of Mechanical Properties of Synthesis Film Using Dynamic Mechanical Thermal Analysis Method

讨论了动态力学热分析测试方法 ,并利用强迫非共振拉伸模式测定了厚度为 37μm的聚酰亚胺 /二氧化硅合成薄膜的力学性能。文章给出了测得的动态杨氏模量随温度的变化曲线 。

The test method of the dynamic mechanical thermal analysis(DMTA) is discussed in this paper.The mechanical properties of the polyimide/SiO 2 composition film of a thickness of 37 μm is measured by a forced non resonance tension mode.Test results are satisfied.A curve of dynamic Young's modulus vs temperature is given in this paper.
