Title: Yukihiro Watanabe: Propeller Shaft Innovation.
Introduction
Yukihiro Watanabe is an inventor associated with Shizuoka, Japan. His patent work includes an engineering design for a propeller shaft that combines metal and fiber-reinforced plastic.
Latest Patents
Watanabe is credited with 1 patent: “Propeller Shaft and Method of Producing the Same.” The invention describes a metal pipe with a joint element attached at one end. A fiber-reinforced plastic layer is formed around the pipe to provide the flexural rigidity needed to meet a required natural bending frequency, while the metal pipe meets the propeller shaft’s required static torsional strength. The layer’s reinforcing-fiber-to-matrix interface strength is specified as 20 to 200 MPa, measured using the microdroplet method.
Career Highlights
The patent reflects an approach to propeller shaft design that balances bending performance and torsional strength through the use of complementary materials. The available information does not identify Watanabe’s employer.
Collaborations
Tsuneo Takano and Kazuhiko Yoshida are listed as Watanabe’s coworkers. The available information does not specify their roles in the patent or their particular contributions.
Conclusion
Yukihiro Watanabe’s documented patent presents a composite-material approach to propeller shaft construction, combining a metal pipe with a carefully specified fiber-reinforced plastic layer.
