On Board 70 MPA Hydrogen Composite Pressure Vessel Safety Factor


The safety factor of a composite structure in relation to its mechanical rupture is an important criterion for the safety of a 70 MPa composite pressure vessel for hydrogen storage, particularly for on-board applications (car, bus, truck, train…). After an introduction of Type IV technology, the contribution of carbon fibre, composite material, structure, manufacturing process of pressure vessels and environmental effects on the safety factor are commented. Thanks to an experimental-based evaluation on composite material and H2 composite pressure vessel, the safety margins are addressed.
