    Type IV hydrogen gas cylinders feature a plastic (polymer) liner, often polyamide, fully wrapped with carbon fiber reinforced resin, designed for high-pressure hydrogen storage up to 950 bar. These, lightweight, corrosion-resistant, and non-metallic vessels eliminate hydrogen embrittlement, offering safer, more efficient storage for automotive,, drone, and transportation applications compared to metal-lined counterparts. 
    Key Characteristics and Benefits 
    • Construction: These are Type IV composite overwrap pressure vessels (COPVs) featuring a plastic liner to prevent gas permeation, fully reinforced with carbon fiber to manage high pressure. Only the neck is typically metal.
    • Performance: Capable of withstanding pressures between 700 and 950 bar.
    • Weight Reduction: Significantly lighter than Type I, II, or III cylinders, enhancing vehicle fuel efficiency.
    • Safety & Durability: The non-metallic, polymer liner eliminates hydrogen embrittlement. They provide high corrosion resistance and superior fatigue resistance.
    • Applications: Primarily used for hydrogen fuel storage in passenger vehicles, trucks, and drones. 
    Manufacturing and Components 
    • Liner: Usually constructed from polymers like polyamide or high-density polyethylene.
    • Overwrap: Carbon fiber, or a carbon/glass fiber blend, is used for the structural wrap, increasing the pressure-bearing capacity.
    • Process: Filament winding techniques are used to apply fiber layers, with specialized, non-destructive testing (NDT) like terahertz imaging for quality control.
