PREPARATION AND PROPERTIES OF MESOPHASE PITCH-BASED RIBBON-SHAPED CARBON FIBERS
|
Abstract:
Ribbon-shaped fibers were melt-spun by petroleum-and naphthalene-basedmesophase pitches, respectively The pitch fibers were stabilized and carbonized. It was shown that ribbon-shaped pitch fibers were formed easily and owned higher orientation than circular fibers. Thethin pitch fibers needed lower stabilization temperature and shorter holding time than circular fibers- The mechanical properties of ribbon-shaped carbon fibers were improved because they have small flaws and highly oriented alignment.
