It is definite that stabilization conditions such as stabilization temperature, time, and heating rate, as well as partial pressure of oxygen, are very influential in the formation of a skin-core structure in carbonized fibers about 10 urn in diameter, defining the thickness of the skin as well as t
Fourier transform infrared photoacoustic spectroscopy (FT-IRIPAS) was used for the characterization of the petroleum pitch, the green fiber, and the stabilization and carbonization processes of the petroleum pitch precursor carbon fiber. Various substituted aromatic ring structures, saturated and un
Stabilization is an important step for producing pitch-based carbon fiber. In this paper, gas formation rates and weight change during oxidative stabilization, which is most commonly employed as the stabilization method, were measured continuously for three pitch-based yarns, using a mass spectromet
