Quantitative testing method for binding force of fiber coating

The invention discloses a quantitative test method for binding force of a fiber coating. The quantitative testing method comprises the following steps: coating the surface of a first section of a fiber coating with a solid inclusion; removing the fiber coating of the second section close to the two sides of the inclusion, and completely exposing the fiber matrix of the second section along the circumferential direction; and pulling the fiber matrix out of the inclusion, measuring a pulling force value when the fiber matrix is pulled out, and calculating the binding force of the fiber coating by combining the diameter of the fiber matrix, the coating length of the inclusion and the pulling force value. According to the quantitative testing method provided by the invention, the wrapping body is formed on the surface of the coating, the fiber coatings on the two sides of the wrapping body are completely removed, so that the wrapping body fixes and positions part of the fiber coatings, and then the binding force
