Abstract
Carbonaceous fiber production method, comprising the passage of a multifilament sheet or tow of precursor fiber through an oxygenation zone, having at least two stages, namely a first stage in which the precursor fiber is brought into contact with oxygen or with a gas containing it and heated to a first temperature at which the fiber can absorb oxygen without degradation, staying at that temperature, and a second stage in which the partially oxygenated fiber is heated in the presence of oxygen to a second upper temperature, at whose temperature it is maintained, passing the fiber through said zone in sufficient state of tension face avoiding its contraction during heating and oxygenation; and the further passage of the fiber through a carbonizing zone in which the fiber is heated to a high temperature under non-oxidizing conditions, to give a fiber of an average young's modulus of 25 x 106 pounds per square inch (1.75). X 106 kg/cm2) at least and an average tensile strength of 250,000 pounds per square inch (17,500 kg/cm2) at least. (Machine-translation by Google Translate, not legally binding)
