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 ...

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 ...

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

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.

Japanese Journal of Applied Physics, 1986
The diamagnetic susceptibilities of a polyacrylonitryle-based carbon fiber (PAN-CF) and benzene derived carbon fiber (BDF) stepwise heat-treated up to 3000°C were measured between liquid-nitrogen and room temperatures. Total susceptibility (χT) vs reciprocal temperature (1/T) plots for PAN-CF specimens heat-treated beyond 1300°C are entirely in ...

Fibre Chemistry, 2018
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 ...

Carbon fiber reinforced polymer matrix composites can be said to have had their beginning in the 1950s and to have attained the status of a mature structural material in the 1980s. Not unexpectedly, applications in the defense-related aerospace industry were the main driving force for the carbon fiber reinforced polymer matrix composites, followed by ...

Fabrication of carbon fibers from jute fibers by pre-oxidation and carbonization
New Carbon Materials, 2013Low-cost jute-based carbon fibers were fabricated by pre-oxidation and carbonization. The chemical, morphological and crystal structure of the jute fibers during pre-oxidation were investigated by Fourier transform infrared spectroscopy, differential scanning calorimetry, elemental analysis, X-ray diffraction and scanning electron microscopy.

The most fundamental aspect of carbon/carbon technology is the substructure or preform which from design considerations may be referred to as fiber architecture. Fiber architecture is the backbone of composites. It not only imparts rigidity to the composites, but also in combination with fiber properties it determines the properties of the composites ...
