Pressurized gas reservoir i.e. transportable gas bottle, has reinforcement filament winding comprising middle layer with reinforcement fibers arranged with respect to axial direction of casing along angle in range of specific degrees

摘要

The reservoir has a reinforcement filament winding (3) on outer surface of casing. The winding has a polar layer (13) with reinforcement resin fibers placed with respect to an axial direction of the casing along an angle in a range of plus or minus 15 to plus or minus 33 degrees. The winding has a circumferential layer with fibers placed relative to the direction along an angle in a range of plus or minus 87 to plus or minus 93 degrees. A middle layer (33) has reinforcement fibers arranged relative to the direction along an angle in a range of plus or minus 51 to plus or minus 59 degrees. An independent claim is also included for a method for manufacturing a pressurized gas reservoir.
