Abstract

The present study has been undertaken in view of the importance of the right choice of carbon precursor for the matrix of carbon-carbon composites. It presents a correlation of the carbonization process as measured by thermogravimetric means with simple fractionization characteristics of coal-tar pitch. The correlations, based on results of six different pitches, link properties such as the fractional composition and the C/H ratio with the carbon yield of a pyrolysis up to 900°C. They also set criteria by which the "best" pitch may be selected. Further examinations of the effect of variabels such as the rate of pyrolysis, the contributions of individual fractions, and the addition of crosslinking agents such as sulfur, are carried out with the selected "best" pitch.
