Increase of Strength of Interface Between liner and composite in HYdrogen tank - ISIBHY

Project summary

The use of hydrogen as an alternative to fossil fuels is an increasingly popular solution to cope with global warming and meet the goals of reducing CO2 emissions. However, hydrogen tanks have limited performance due to the early detachment of the liner with the composite. The project aims at improving the durability of the wound tank and to delay the optimum use time. The rupture of the interface between the liner and the composite may lead to a situation in which the tank does not longer assure its functionality as a reservoir. The ISIBHY project aims to increase the liner-composite assembly performances by improving the adhesive formulation and performing specific thermomechanical tests to understand the mechanisms at stake in explosive decompression process. Through testing and simulations of interfacial failure, the results are ultimately expected to enable the design of the next generation materials able to sustain the effect of explosive decompression.
