The Change of Amount and Twists Effect to Electrical Performance of Carbon-Coated Filaments
This article analyzed different filament amount and twists effect on the CCFs’ conductivity and stability of resistance under different elongation, and observed the surface of CCFs by SEM. The study demonstrated: In the initial state, the experimental resistance value of CCFs’ is close to the theoretical one; The conductivity would improve as the number of filament and twist adding; The relationship between resistance and elongation varies differently in two periods during the stretching: within 0-6mm, CCFs' varies of resistance is more stable, but unsteadily within 6-15mm, and the coat of some samples began to break off.
