Abstract
Provided is a method for estimating abrasion resistance and fracture resistance by highly accurately analyzing aggregation (dispersion) of sulfur-based materials in polymer composite materials. The present invention relates to a method for estimating abrasion resistance and fracture resistance, the method including: irradiating a polymer composite material containing at least one sulfur-based material selected from the group consisting of sulfur and sulfur compounds with high intensity X-rays; measuring X-ray absorption of a measurement region of the polymer composite material while varying the energy of the X-rays; calculating areas of spots having a high sulfur concentration equal to or greater than a predetermined level in a two-dimensional mapping image of sulfur concentration of the measurement region; and estimating abrasion resistance and fracture resistance based on the areas.
