Book Description
This report presents a cost analysis of Carbon Fiber production from polyacrylonitrile (PAN) fiber. In this process, PAN fiber is first stabilized. The stabilized PAN passes then through carbonization, surface treatment and sizing, before being winded. This report was developed based essentially on the following reference(s): (1) "Fibers, 5. Synthetic Inorganic", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) US Patent 8137810, issued to Toray in 2012; Keywords: Polyacrylonitrile, carbon fiber, acrylic fiber, PAN

Book Description
This report presents a cost analysis of Polyacrylonitrile (PAN) Precursor production. In this process, acrylonitrile is polymerized with methyl acrylate comonomer via aqueous dispersion polymerization and the polymer formed is subsequently converted to fiber through wet spinning. This report was developed based essentially on the following reference(s): (1) "Acrylic Fibers," Encyclopedia of Polymer Science and Technology (2) Morgan, P., Carbon Fibers and Their Composites, 2005 Keywords: Polyacrylonitrile, Carbon Fiber, Acrylic Fiber, Suspension Polymerization, Acrylonitrile, Wet Spinning

Book Description
This report presents a cost analysis of Carbon Fiber production from pitch. The process starts with a preparation step that converts the pitch into mesophase pitch. The mesophase pitch is then stabilized and passes through carbonization, graphitization, surface treatment and sizing, before being wound. This report was developed based essentially on the following reference(s): (1) "Fibers, 5. Synthetic Inorganic", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) US Patent 4999099, issued to Conoco in 2011 (3) Chung, D.D.L., Carbon Fiber Composites, 1994 Keywords: Carbon Fiber, Petroleum Pitch, Coal Tar Pitch, Mesophase Pitch

Book Description
This book describes the application of life cycle assessment (LCA) methodology to streamline analysis of process and material variations in carbon fibre manufacturing, focusing on large-scale continuous production. It reports on a modular LCA concept based on accepted international standards and an in-depth analysis of carbon fibre manufacture. This streamlined assessment approach considers material flows and properties, and generated emissions, throughout the manufacturing process. Further, four manufacturing scenarios for optimizing material throughput are discussed, highlighting trade-offs between production rate, material properties, environmental impact, and cost. In turn (“Subsequently” or a synonym may be more suitable here as this part is not directly linked to what is described in the previous sentence), the evaluation of three precursor materials,traditional PAN, textile-grade PAN, and an experimental bio-based lignin-cellulose blend is described. The strengths and weaknesses, like processability and cost efficiency, of each material are outlined in detail. Overall, this book offers a comprehensive analysis of the effect process and material variations have on carbon fiber manufacture. It also showcases methodologies to optimize these industrial processes for a sustainable production on a large scale.

Book Description
There is tremendous need to integrate carbon fiber composites for light-weighting in the transportation sector, especially for automotive composites and in energy generation space associated with wind turbine manufacturing. Tensile properties of carbon fibers are fundamental to designing fiber reinforced polymers and carbon/carbon composites. Carbon fiber suppliers typically follow general guidelines prescribed in the relevant standards (ASTM D4018) to prepare resin reinforced carbon fiber tows for determining the tensile properties. In this study, the effect of manufacturing process associated with carbon fiber tows was evaluated using two methods involving manual tensioned strands or using automated spool method. Important effects associated with fiber spacing, cross-sectional morphology of the infused tows are reported in this study. Single fiber mechanical properties are determined to obtain relationship from multiple length scales and the role of interfacial behavior between the carbon fiber and resin system using single fiber fragmentation. These results, for the first time, revealed important relationships between single fiber, interface, and infused tow based mechanical properties. A new concept for deformation response of infused tows, limit stress, demonstrated a connection in the nonlinearity nature of tensile modulus seen for carbon fibers in single fiber state and in tow format. Limit stress showed good representation of the relative role of relationships (interfacial behavior, crack propagation, and stress transfer) from limit stress to failure stress. Three low-cost precursors, oxidized PAN, and carbon fiber, from the Carbon Fiber Technology Facility with differences in spin finish and/or tenacity are studied in detail through various stages of oxidative stabilization and carbonization to develop improved understanding of the precursor properties and final textile PAN based carbon fiber properties. A systematic approach consisting of DSC, TGA, FT-IR, XRD, single fiber testing, and infused tow testing were considered in evaluating the process-structure-tensile property relationship for the three precursors. The results identified the role of spin finish and tenacity on the performance of low-cost carbon fiber. This part of the research provides an important conclusion that the carbon fiber manufacturing process using textile PAN precursors is industrially robust and is not strongly dependent on precursor tenacity or surface finish.

Book Description
Having fully established themselves as workable engineering materials, composite materials are now increasingly commonplace around the world. Serves as both a text and reference guide to the behavior of composite materials in different engineering applications. Revised for this Second Edition, the text includes a general discussion of composites as material, practical aspects of design and performance, and further analysis that will be helpful to those engaged in research on composites. Each chapter closes with references for further reading and a set of problems that will be useful in developing a better understanding of the subject.

Book Description
Carbon fibers have unique properties that include high strength, low density and excellent chemical and thermal resistance. However, they have a low level of utilization because of their high price; typically around $30/kg for an entry level polyacrylonitrile (PAN) based carbon fiber. Low-cost carbon fibers derived from lignin are currently being investigated at the University of Tennessee, because using lignin as a precursor could significantly reduce production costs. Lignins obtained from the pulp and paper and the emerging biofuel industries have the potential to be used for carbon fiber production, however, they are typically unsuitable because of the high levels of impurity and variable thermal properties. This research study examines the potential of a novel organosolv process to provide high purity lignin for carbon fiber production. This fractionation separates woody and herbaceous bioenergy crops into their three main components: cellulose, hemicellulose, and lignin, each of which can be used within the biorefinery for the production of fuels or chemicals. In this program, organosolv derived lignin from both tulip poplar (Liriodendron tulipifera) and Alamo switchgrass (Panicum virgatum) were recovered and compared as starting materials for carbon fiber. The organosolv derived lignin was analyzed using several different methods to assess quality differences for potential carbon fiber manufacture. Their purities, chemical structures, consistencies, thermal, and carbonization properties were evaluated and lignin exhibiting optimal properties was used for fiber spinning and conversion to carbon fiber. Lignin exhibiting the best thermal performance was achieved by isolation at 150°C to 170°C with an acid concentration of 0.05 and 0.1 M H2SO4, and a fractionation time of 120 and 180 minutes. Organosolv fractionation conditions and their influence on the properties of lignin-based carbon fiber are presented in this thesis.
