Measurement of Resistivity of Conductive Fiber Using Density Method
Conductive fiber is the focus of research in the industry because of its low resistivity and high strength.This article provides a test method for measuring the volume resistivity of conductive fibers using the volumetric density method.In the method,first test the density α,the mass m,length L,and resistance R of the fiber bundle,and then calculate the resistivity ρ of conductive fiber using a calculation formula ρ=mR/αL2 On this basis,this article proposes a calculation model for the ratio of conductive fiber units to insulating fiber units based on the resistivity and density data of conductive fiber.
