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.

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.

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.

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 ...

Carbon fiber (CF) is increasingly attracting the interest of composites industry for future applications in automotive, wind, and transportation. The reason of this interest is mainly based on CF's unique properties. They are strong and durable in addition to light in weight. All of these cannot be replaced by a single fiber type. In this chapter, each

Electrochemistry at carbon fibers
Analytica Chimica Acta, 1981Carbon fibers are proposed as a support electrode for a mercury film electrode. The response of these electrodes is evaluated for use in differential pulse anodic stripping voltammetry. The mercury film is deposited in situ in aqueous solution and used to quantify cadmium in solutions of cadmium salts and organo cadmium compounds in the 1–10 μg l-1 ...

Abstract : Various spinning trials of polyacrylonitrile (PAN) and PAN/carbon nanotube (CNT) fibers were conducted using single- and bi-component spinning to obtain precursor fiber for carbonization. Materials parameters, such as homo- vs co-polymer, as well as different molecular weight polymers were investigated.

Many publications characterizing historical and technological aspects of activated carbon fiber production are reviewed. Issues with using various fiber precursors to produce sorbents are discussed. Solid-state activation, the search for new precursors, and the development of highly filled sorbents are identified as several applications of promising ...
