Title:
HYDROGEN-DISPENSING HOSE
Document Type and Number:
WIPO Patent Application WO/2016/199643
Kind Code:
A1
Abstract:
Provided is a hydrogen-dispensing hose, in which pressure resistance and durability can be improved while minimizing any disturbance to, and internal-pressure-induced dimensional changes in, reinforcing layers in a portion where a hose fitting is crimped. At least two reinforcing layers (3) are coaxially laminated between an inner surface layer (2) made of a thermoplastic resin having a gas transmission coefficient of no more than 1×10–8cc·cm/cm2·sec·cmHg for dry hydrogen gas at 90°C, and an outer surface layer (4) made of a thermoplastic resin. A wire-braided layer (3m) formed by braiding metal wires (m) is used on the outermost periphery of the reinforcing layers (3). Fiber-braided layers (3a, 3b) formed by braiding high-strength fibers (f) such as PBO fibers are used on the other reinforcing layers (3).
