Latest Patents

Hall's latest patents focus on the process for the manufacture of carbon fibers and the feedstock required for their production. One of his key innovations involves an improved pitch that is designed to create readily stabilizable, substantially nonmesophasic carbon fibers. This pitch has a softening point of approximately 250 degrees Celsius (480 degrees Fahrenheit) or higher. It is produced from an unoxidized thermal petroleum pitch by selectively reducing or eliminating low molecular weight materials in a very short time frame. This process minimizes the tendency to produce mesophase pitch while preserving the chemical integrity of the higher molecular weight fractions. Additionally, Hall has disclosed methods for producing carbon fibers, as well as rovings or mats derived from these fibers.
