Automated Tape Layup Manufacturing of Carbon fibre reinforced Hydrogen storage tank

17 Nov 2025

The increasing demand for hydrogen gas as fuel has led researchers to develop lighter and stronger materials, intended for safely storing hydrogen in liquified form at cryogenic temperatures. One of the most preferred and lightest material is carbon fibre composite, whose properties can be customized according to the pressure requirements for storing liquified hydrogen (H2). This research work is focused on developing thermoplastic composites by automated tape laying process (ATL) having maximum gas permeability levels of 4 x 10-14 H2 mol/s to store hydrogen H2 in linerless carbon composite tanks at cryogenic temperatures.

Carbon fibre (CF) with polyamide 11 (PA11) matrix was used to manufacture thermoplastic composites using  automated tape laying process. The manufactured composites were treated in autoclave and tested for hydrogen permeability at room temperature. 

The results show that autoclave cured CF/PA11 composites meet the set permeability requirements for composite hydrogen storage vessel designed for pressure of 6 bar.
