摘　　要：研究了湿热老化和盐雾老化对聚对苯二甲酸乙二醇酯(PET)薄膜拉伸性能的影响。结果表明,随着湿热老化试验时间的增加,PET薄膜的拉伸强度呈现先增大后减小的趋势,断裂伸长率则呈现先减小、然后增大、再减小的趋势;而随着盐雾试验时间的增加,PET薄膜的拉伸强度和断裂伸长率均逐渐减小。The effects of damp heat and salt mist aging on the tensile property of polyethylene terephthalate （ PET） were studied. It has been found with the increase of damp heat aging time that the tensile strength showed a trend of first increase and then decrease,and the elongation at break exhibited a trend of first decrease,then in-crease and decrease subsequently,while the tensile strength and elongation at break both deceased with the increase of salt mist aging time.
