Heterogeneities in carbon fibers

Carbon, 1975
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 to 3000 A.

Wettability of a Single Carbon Fiber

Langmuir, 2016
A new method was developed to measure the dynamic contact angles of a single carbon fiber at low and high velocities, taking into consideration both the intrinsic variability of the carbon fiber diameter and the extremely small amplitude of the capillary forces. The effectiveness of the method was strengthened by fitting the experimental contact angle ...

Lyocell fibers as the precursor of carbon fibers

Journal of Applied Polymer Science, 2003
AbstractIn this work, Lyocell fibers, used as carbon fiber precursors, were investigated. Lyocell fibers used for the carbon precursors and the carbon fibers themselves were produced in our laboratory. The mechanical properties morphology and structure of the precursors and the obtained carbon fibers were studied and compared to those of rayon.

Coating of Carbon Fibers—The Strength of the Fibers

Journal of the American Ceramic Society, 1995
The 6k carbon fiber Torayca T800H was coated with pyrolytic carbon by a CVD process. Fiber bundles were tested and evaluated. By this procedure, the whole distribution of the failure probability with respect to the fiber strength is obtained in a single experiment.
