Title: Masaki Narisawa: Innovator in SiC Fiber Production
Introduction
Masaki Narisawa is a prominent inventor based in Osakasayama, Japan. He has made significant contributions to the field of materials science, particularly in the production of silicon carbide (SiC) fibers. His innovative approach has implications for various applications, including composite materials that require enhanced toughness and heat resistance.
Latest Patents
Narisawa holds a patent for a process for producing reinforcing SiC fiber for SiC composite material. The patent describes a method where a mixed polymer liquid is prepared by combining a polycarbosilane-dissolved organic solvent with poly(methylsilane). This mixture is moderated to a viscosity of 5–20 Pa·s through heat treatment, promoting a partial cross-linking reaction. The mixed polymer is then melt-spun into fiber at temperatures ranging from 250–350°C. The fiber undergoes curing at 100–200°C in an oxidizing atmosphere and is subsequently baked at 1000°C or higher. This innovative process allows for continuous melt-spinning of SiC fiber without breakage, resulting in a material that is useful for reinforcing SiC composites, which exhibit excellent toughness, strength, and heat resistance.
