Effect of stabilization conditions on mechanical properties of carbon fiber

Abstract

Polyacrylonitrile (PAN) precursor fibers were spun and stabilized using continuous tailor-made stabilized system with a total duration of 45 to 110 min. Stabilization temperature varied stepwise from 195 to 280°C. Stabilized fibers were carbonized in nitrogen atmosphere at 1200°C in a furnace. An effect of stabilization time on tensile strength and modulus was observed in a given stabilization system.
