Title:
METHOD FOR EVALUATING SHEET BREAKAGE OF POLYMER COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JP2018114649
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an evaluation method capable of accurately evaluating the frequency of occurrence of sheet breakage of a polymer composite material at a laboratory level.SOLUTION: The method for evaluating sheet breakage of a polymer composite material includes evaluating the frequency of occurrence of sheet breakage on the basis of the degree of orientation of the polymer in the polymer composite material after roll forming obtained by irradiating the polymer composite material with high-intensity X-rays and calculating the degree of orientation of the polymer on the basis of an amount of X-ray absorption that is measured while X-ray energy is changed.SELECTED DRAWING: Figure 1
