The Department of Energy Partnership for a New Generation of Vehicles has shown that, by lowering overall wt., the use of carbon fiber composites could dramatically decrease domestic vehicle fuel consumption. For the automotive industry to benefit from carbon fiber technol., fiber prodn. will need to be substantially increased and fiber price decreased to $7 / kg To achieve this cost objective, alternate precursors to pitch and polyacrylonitrile (PAN) are being investigated as possible carbon fiber feedstocks. Addnl., sufficient fiber to provide 10 to 100 kg for each of the 13 million cars and light trucks produced annually in the U. S. will require an increase of 5 to 50-fold in worldwide carbon fiber prodn. High-vol., renewable or recycled materials, including lignin, cellulosic fibers, routinely recycled petrochem. fibers, and blends of these components, appear attractive because the cost of these materials is inherently both low and insensitive to changes in petroleum price. Current studies have shown that a no. of recycled and renewable polymers can be incorporated into melt-spun fibers attractive as carbon fiber feedstocks. Highly-extrudable lignin blends have attractive yields and can be readily carbonized and graphitized. Examn. of the phys. structure and properties of carbonized and graphitized fibers indicates the feasibility of use in transportation composite applications. [on SciFinder(R)]
