Latest Patents

Atsumi holds a notable patent titled "Process for Manufacturing Prepregs for Use as Electric Insulating." This invention outlines a comprehensive method for creating a prepreg that serves as an electrically insulating material. The process involves the separate filtering and metering of a main epoxy resin composition and a subsidiary resin composition containing a hardener. These components are then quickly mixed to create a resin composition, which is applied to a reinforcing member using a die coater. This method ensures a uniformly thin film under specific temperature and low shear conditions. The coated member is then subjected to non-contact heating via an infrared ray heater for resin impregnation, followed by additional heating through a floating dryer to achieve semi-hardening. Ultimately, the member is compacted into a sheet-shaped fiber-reinforced composite, showcasing the efficiency and effectiveness of Atsumi's invention.
