Document Type and Number:
WIPO Patent Application WO/2020/036000
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a method for analyzing a fiber structure comprising fiber and inorganic particles. This analysis method is a method for evaluating a structure including fiber and inorganic particles. The method comprises: (A) a step for using a scanning electron microscope to acquire a two-dimensional image of the surface of a fiber structure, (B) a step for removing contrast value noise from the acquired image, and (C) a step for calculating the standard deviation of the contrast values after the noise has been removed.
