The electric resistance of fibre assemblies
Yao Mu · 2001
First, the physical model of electric conductivity of bibre agglomerates is built when it' s compressed along lengthwise and crosswise. Accordingly, the mathematical model is established, and derives a equation between fibre agglomerates resistivity ρ and rate of filling f, the equation corresponds to the practical variation. The resistiving is equal in value for fibre agglomerates to compress along lengthwise and crosswise. The cause of ρ varying along tht f is that the number of passageways of conducting electricity gradually increases and the average valid length of every passageway is shortened ρ-1-f curve is S shape, the middle part is approximate straight line, there is a small error between f=0. 15 and f= 0. 45 to use struaight line.
