Abstract
A method and an apparatus for manufacturing a linerless pressure vessel can be used for manufacturing a high pressure tank, by spinning of continuous fiber in a centrifugal direction.
Claims16
A method for manufacturing a linerless tank installed with a three-dimensional blow fibrous structure woven with resin-impregnated fiber, comprising:
- the resin-impregnated fiber being spun in a mold and settled in an inner surface of the mold;
- a spinning unit spinning the fiber in a circumferential direction by centrifugal force;
- the spinning unit moving and rotating along a moving shaft in the mold;
- and
- the three-dimensional blow fibrous structure being manufactured in a blow form and woven along an inner profile of the mold, wherein
- a viscosity of the resin impregnated in the fiber is 0.01 to 100 Pa·s, and
- the resin is at least one thermosetting resin selected from a group consisting of:
- isophthalic polyesters, vinyl esters, epoxies, polyesters, and polyurethanes.

An apparatus for manufacturing a linerless high pressure tank installed with a blow fibrous structure as a resin-impregnated fiber textile, comprising:
- a fiber used for braiding or filament winding, which is resin-impregnated before being spun from a nozzle;
- the nozzle for spinning the fiber is combined with a spinning unit with a degree of freedom of 1 or 2, so as to be monoaxially or biaxially tilted at the tip of the spinning unit;
- the spinning unit configured to move forward and backward and rotate on a central axis, wherein the fiber moves to the nozzle through a blow part;
- and
- a mold for manufacturing blow-type parts, which includes an upper part and a lower part, and in which the fiber spun from the nozzle is wound or woven along the internal shape of the mold.
