摘要

摘要: 在Г·М·古尼耶夫中值老化公式的基础上,采用回归分析方法对碳纤维/环氧树脂基复合材料的实验室模拟加速腐蚀与自然大气腐蚀之间的相关性进行研究,确定了自然大气环境腐蚀试验的层间剪切强度的中值曲线方程,并得出实验室模拟加速腐蚀与自然大气环境腐蚀之间的当量关系.试样表面及断口微观形貌的观察分析进一步证明:实验室模拟加速腐蚀与自然大气环境腐蚀具有相似的腐蚀机理.

Abstract: On the basis of the Г.M. Gunyaev’s equation of average aging life, a study of the relativity between the simulated and accelerated corrosion and the natural environment corrosion for the carbon fiber/epoxy composite was carried out by using regression analysis method. The equation of average aging life of the residual interlaminar shear strength of the natural environment corrosion specimens was determined, and the equivalent relation between the simulated and accelerated corrosion and the natural environment corrosion was obtained. The analysis of the surface and fracture morphologies of the carbon fiber/epoxy composite specimens further reveals that the corrosion mechanism of the simulated and accelerated corrosion is similar to the natural environment corrosion.
