摘要
Abstract
This article mainly discusses the causes of thermal deformation temperature failure of PA66 materials.The composition information of the material was obtained through analysis methods such as infrared spectroscopy,pyrolysis spectra,and DSC curves.At the same time,physical performance such as thermal deformation temperature,tensile strength,and impact strength of the material were tested.The crystal morphology of the material was observed under a polarizing microscope.The results indicated that the failed sample was a glass fiber reinforced material mixed with PA66 and PA6.Under the blending,the original crystalline morphology of PA66 was destroyed,and the blending ratio of the two was inappropriate.This leads to premature failure of the material during use.关键词
