초록
Polyacrylonitrile (PAN) fibers are the most widely used precursor of the materials forcarbon fibers. The conventional process of carbon fibers from PAN precursor fiber includes twostep; stabilization at low temperature and carbonization at high temperature. Compared to thermalstabilization, the stabilization process by electron beam (E-beam) irradiation is a advancedand brief method. However, a stabilization by E-beam irradiation was required a high dose (over5,000 kGy) and spend over 1.5 hr (1.14 MeV, 1 mA). In the present work the main goal is exploringa quick stabilization process by cotrolling E-beam currents. The effect of various E-beam currentson stabilization of PAN precursor fiber was studied by gel fraction test, thermo gravimerticanalysis (TGA), differential scanning calorimetry (DSC), tensile strength, and scanning electronmicroscopy (SEM) images.
Abstract
Polyacrylonitrile (PAN) fibers are the most widely used precursor of the materials forcarbon fibers.

However, a stabilization by E-beam irradiation was required a high dose (over5,000 kGy) and spend over 1.5 hr (1.14 MeV, 1 mA). In the present work the main goal is exploringa quick stabilization process by cotrolling E-beam currents.
