Polyfilamentary carbon fibers and a flash spinning process for producing the fibers

A process for preparing fibers, including: (a) providing a spinning mixture including a dispersion of a flashing agent and an excess of a carbonaceous pitch; and (b) passing the spinning mixture from a high pressure region through an orifice to a low pressure region to form polyfilamentary pitch fib...

Summary:A process for preparing fibers, including: (a) providing a spinning mixture including a dispersion of a flashing agent and an excess of a carbonaceous pitch; and (b) passing the spinning mixture from a high pressure region through an orifice to a low pressure region to form polyfilamentary pitch fibers. The pitch fibers may optionally be further treated to form polyfilamentary carbon fibers or graphite fibers, which may be incorporated into a resin to form a lightweight, conductive composite.
