Lyocell fibers as the precursor of carbon fibers
Journal of Applied Polymer Science, 2003AbstractIn 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.

Tension of carbonization for carbon fiber
Polymer Engineering & Science, 1994AbstractThe mechanical properties of carbon fiber, especially tensile modulus, are closely related to the orientation of crystals. Hence, the stretching of carbon fiber during carbonization is of importance. In this study, the tension arm between the carbonization furnaces was used to stretch carbon fiber.

Coating of Carbon Fibers—The Strength of the Fibers
Journal of the American Ceramic Society, 1995The 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.

MRS Proceedings, 2001
AbstractWe briefly review some methods recently proposed to make films and fibers of preferentially oriented carbon nanotubes. We discuss in more detail a simple spinning process which consists in dispersing the nanotubes in a surfactant solution, re-condensing the nanotubes in the flow of a coagulating polymer solution to form a nanotube mesh, and ...

Pitch-based carbon fibers, using pitches as raw materials, can have various characteristics derived from the properties of the original pitch and production method of the fibers. This chapter explains the types, manufacturing method, and also characteristics and structural features of the pitch-based carbon fibers, emphasizing the very high elastic ...

Journal of the Mechanics and Physics of Solids, 1994
Abstract The mechanical properties for carbon fibers are determined in terms of the elastic moduli of single crystal graphite. This is done for the two basic fiber microstructures, radial and onion skin. The final results are found through a transformation from cylindrically orthotropic to transversely isotropic properties.

Electrodes of the smallest characteristic dimensions less than few micrometers have unique properties which make them very attractive for use in many electrochemical and biomedical applications. Because of the response of these small electrodes it is possible to change their properties drastically just by variation of the electrode diameter.
