Title: Kenji Hayashi: Innovator in Fiber-Reinforced Plastics
Introduction
Kenji Hayashi is a notable inventor based in Tochigi, Japan, recognized for his contributions to the field of fiber-reinforced plastics. With a total of five patents to his name, Hayashi has made significant advancements in molding techniques that enhance the efficiency and quality of molded articles.
Latest Patents
Hayashi's latest patents include an innovative FRP sheet press molding method and device, as well as an FRP molded article. The FRP sheet press molding method allows for improved yield without the need for mold opening and closing adjustments after clamping. This method involves a press step where molds are closed, and a heated sheet material is press-molded inside a cavity. Following this, a filling step is executed, maintaining the closed state of the molds while a molten resin is pressure-injected into the gap between the sheet material and the cavity. This process ensures that the surfaces of the sheet material and the molten resin come into contact with the cavity, resulting in a high-quality molded product.
The fiber-reinforced resin molded article is designed to take on a three-dimensional shape based on a sheet-shaped base material containing fiber-reinforced resin. This article features three-way directed corner portions made up of plate sections joined in different directions. The design includes wrinkles that protrude from the corner portions, created by folding the sheet base material, along with thick-walled sections laminated at sites where the wrinkles form.
