Abstract
Provided is a method for estimating abrasion resistance of polymer composite materials. The present disclosure relates to a method for estimating abrasion resistance, the method including: irradiating a sulfur compound-containing polymer composite material with high intensity X-rays; measuring an X-ray absorption in a small region of the polymer composite material while varying an energy of the X-rays, whereby a dispersion state and a chemical state of the sulfur compound are analyzed; and quantifying an inhomogeneous state of cross-link degradation in the polymer composite material based on the dispersion state and the chemical state.
Claims5
A method for estimating abrasion resistance, the method comprising:
- irradiating a sulfur compound-containing polymer composite material with high intensity X-rays;
- measuring an X-ray absorption in a small region of the polymer composite material while varying an energy of the X-rays, whereby a dispersion state and a chemical state of the sulfur compound are analyzed;
- and
- quantifying an inhomogeneous state of cross-link degradation in the polymer composite material based on the dispersion state and the chemical state,
- wherein the quantifying the inhomogeneous state of cross-link degradation is performed by calculating a degree of inhomogeneity of cross-link degradation using the following (Relationship 1):
- (Degree of inhomogeneity of cross-link degradation)=SOA/SOM (Relationship 1)
- where SOA represents a sulfur oxide content of a sulfur-aggregated portion in the polymer composite material, and SOM represents a sulfur oxide content of a matrix portion in the polymer composite material.
