Filament winding hydrogen tanks (Thermoset)

Updated: Nov 6, 2022



Production of hydrogen tanks has been done using wet/dry filament winding for many decades now. This article focuses on describing the filament winding with the Wet and Towpreg approach. Highlighting the benefits of each process. Towards the conclusion, the article directs toward the complete course for Design and Development of Compressed Hydrogen Storage Tanks.

Winding Methodology

Filament Winding

Filament winding is a technique primarily used to manufacture hollow, circular, or prismatic parts such as pipes and tanks. It is performed by winding continuous fiber tows onto a rotating mandrel using a specialized winding machine. Filament wound parts are commonly used in the aerospace, energy, and consumer product industries.
