Latest Patents

One of Yusuke Kuji's latest patents is a method for manufacturing a carbon fiber bundle. This method includes a stabilization process that subjects an acrylic fiber bundle to a heat treatment within a range of 200° C. to 300° C. in an oxidizing atmosphere. It also involves a pre-carbonization process that performs heat treatment within a range of 300° C. to 1,000° C. using a specialized heat treatment furnace. This furnace has at least one inert gas supply port on each side of the fiber bundle and at least one exhaust port between the supply ports. The carbonization process then takes place at temperatures ranging from 1,000° C. to 2,000° C. in an inert gas atmosphere. This innovative method allows for continuous manufacturing while preventing the entry of gasified decomposition products, such as tar, into the temperature zone.

Another notable patent is a method of producing a flame-resistant fiber bundle and carbon fiber bundle. This method involves heat-treating an acrylic fiber bundle in a heat treatment chamber where hot air is circulated. The process ensures that the acrylic fiber bundle runs on direction-changing rollers while being treated with hot air supplied in a specific manner to enhance the production of oxidized fiber bundles.
