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.

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 ...

Carbon Fiber/Carbon Matrix Composites
2012We devote this chapter to a very special kind of composite that consists of carbon fibers embedded in a carbonaceous matrix. The carbon fiber in these composites can be continuous or short. We described the processing of carbon fibers in Chap. 2. Carbon is a very versatile material.

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.

Carbon Fibers and Their Composites
2014Traditionally, the application of carbon fibers has been limited to very special fields such as aerospace and military because of their high cost. However, various techniques for low-cost carbon fibers are under development in terms of using low-cost precursors, low-cost manufacturing processes, and even functional coating methods.
