This was no easy task. Diaphragm thickness and diameter are 0.635mm ±0.10 and 72.13 mm respectively with nylon cloth inside.The three-layer structure is created by compression molding on both sides of a nylon cloth with special rubber that we have developed. This diaphragm sends fuel to the engine using pressure fluctuation –very thin. However, high durability is required.
Accuracy and reliability are important for use in space.
KEF provides a scholarship to a Master's student studying Polymer chemistry, aiming at developing rubber with no environmental impact. The Nikkan Kogyo Shimbun (Feb. 2020 Japan Industry Newspaper)
