Heterogeneities in Carbon Fibers.
Abstract
Acrylic fibers, stabilized acrylic fibers and graphite fibers have been selectively etched by ion bombardment. After ion etching, the fibers are characterized by structures oriented transverse to the fiber axis with an average spacing ranging from 500-3000 A. These transverse structures are considered to be representative of structural inhomogeneities in the fibers, which are transmitted from the precursor fiber through the stabilization treatment to the final carbon fibers. The relation between these heterogeneities and the standard microstructural models of carbon fibers remains to be elucidated satisfactorily. (Author)
