Evolution of chemical structure and out gases of isotropic pitch fibers were studied in terms of stabilization. As stabilization plays an important role in the mechanical properties of carbon fibers (CF), thermogravimetric analysis was performed to optimize the duration and temperature of stabilization in this study. Fourier transform-infrared spectroscopy was applied to investigate chemical structure and formation of O2 containing functional groups during the stabilization. In addition, mass spectrometry showed that O2 uptake started at around 150 ℃ along with formation of various gases such as CO, CO2, and H2O. The longer stabilization resulted in higher tensile strength of the pitch fiber with higher strain-to-failure due to intermolecular crosslinking reactions leading to a network formation of pitch molecules. The stabilized fibers were carbonized at 1500 ℃ in a furnace under nitrogen atmosphere. Maximum tensile strengths of ~900 MPa were obtained from CF stabilized for 60 min at 280 ℃.
