Deterioration Acceleration Method and Deterioration Acceleration Device

Abstract

In a degradation acceleration method for accelerating composite degradation of a polymer material, a first step of applying, by an additional device (light source), an environmental degradation factor including light to the polymer material, a second step of applying, by a bending mechanism, a repeated bending stress to the polymer material, and a third step of measuring, by a measurement device (control device and infrared spectroscopic analysis device), a degradation progress state of the polymer material on the basis of an infrared spectroscopic analysis result of the polymer material are performed.
