Piezoresistance of Graphite Fibers

Abstract

Electrical resistance of graphite fibers under tensile load was measured. It was found that the resistance of low-modulus fibers increased with tensile strain, while the resistance of ultra high-modulus decreased with tensile strain. The effect of torsional strain upon resistance was also studied.

Keywords
