Latest Patents

Among his latest patents is a process for the manufacture of carbon fibers and feedstock therefor. This patent discloses an improved pitch for making readily stabilizable, substantially nonmesophasic carbon fibers. The pitch has a softening point of about 250°C (480°F) or above and is produced from an unoxidized thermal petroleum pitch. The process involves selectively reducing or eliminating a portion of the low molecular weight materials in a very short period of time. This method helps to eliminate or reduce the tendency to produce mesophase pitch while preserving the chemical integrity of the components of the higher molecular weight fractions. Additionally, the patent outlines a method of producing carbon fibers and rovings or mats from such fibers.
