Graphite Fibers from Pitch

Abstract

Methods to measure molecular weight distributions in MP pitches have been developed. Number and weight average molecular weights and their distributions have been deter-mined as a function of P.I. in MP pitches. Significant progress has been achieved during this report period both in the art of spinning very thin MP pitch filaments and in the understanding of structural changes that take place during the conversion of pitch fibers to high- performance carbon fibers.
