Latest Patents

Nayuki's latest patents include a method for producing high strength, high modulus mesophase-pitch-based carbon fibers. This method enables the production of carbon fibers at relatively low temperatures while maintaining a stabilized production process. The first stage involves carbonizing infusibilized fibers in an inert atmosphere, either under no tension or a minimal tension of 1 mg/denier. This process results in a specified interlayer spacing and crystallite thickness. The second stage requires carbonizing under a tension of 50-300 mg/denier at temperatures exceeding 2600°C. Another patent focuses on producing carbon fibers with a modulus of elasticity of 75 tonf/mm² or more and a tensile strength of 250 kgf/mm² or more. This method involves graphitizing mesophase-pitch-based carbon fibers at high temperatures while stretching the fibers according to specific relations.
