Title: Hiroyuki Kuroda: Innovator in Carbon Fiber Technology

Introduction

Hiroyuki Kuroda is a notable inventor based in Oomiya, Japan. He has made significant contributions to the field of carbon fiber and graphite fiber production. With a total of 2 patents, Kuroda's work has advanced the technology and applications of these materials.

Latest Patents

Kuroda's latest patents include a process for producing carbon fiber and graphite fiber. This innovative process involves spinning a carbonaceous pitch, doubling spun pitch fiber bundles, and adding a heat-resistant doubling treatment oil. The fiber bundles are then passed continuously through an oxygen-rich gas, infusibilizing at a temperature of 350 degrees Celsius or less, followed by carbonization or graphitization of the infusibilized fiber bundles. Another significant patent is for producing extremely high modulus pitch-based carbon fibers. This method allows for carbonization at a substantially lower temperature, around 2500 degrees Celsius, by selectively stabilizing only the outer surface layer of the fiber while keeping the inner portion non-stabilized.

Career Highlights

Throughout his career, Kuroda has worked with prominent companies such as Toa Nenryo Kogyo and Toa Nenryo Kogyo, K.K. His expertise in carbon fiber technology has positioned him as a key figure in the industry.
