Latest Patents

Hashimoto holds a patent for a "Method for producing a hollow FRP article." This patent describes a process for creating hollow resin shells through blow molding. The method involves filling the interior of the resin shell with heat-resistant fine particles, decompression to form an inner mold, and covering the inner mold with FRP prepreg that includes thermoplastic resin. The prepreg composite is then heated in a metallic mold under pressure, allowing for the removal of fine articles after demolding. Additionally, he has developed a technique for forming a golf club shaft by heating a mandrel and applying thermoplastic resin powder, followed by winding a lamellar prepreg around the mandrel.
