Abstract
Disclosed are a method of spinning a continuous fiber without a mandrel to manufacture a hollow cylinder part and an apparatus for manufacturing the hollow cylinder part using the same method.
Claims14
A method of weaving a fiber impregnated with resin to manufacture a three-dimensional hollow fiber structure,
- wherein the fiber impregnated with resin is spun within a mold to seat on an internal surface of the mold,
- wherein a spinning unit spinning the fiber moves along and rotates about a traveling shaft within the mold,
- wherein the fiber is spun in the circumferential direction by a centrifugal force, and
- wherein the three-dimensional fiber structure is weaved along the internal shape of the mold.
1 more element
An apparatus for manufacturing a hollow fiber structure as a weaved fiber impregnated with resin, comprising;
- a nozzle spinning a fiber;
- a spinning unit coupled with the nozzle, wherein the spinning unit has a hollow central portion, moves forward and backward, rotates about a central shaft, and allows the fiber to move toward the nozzle through the hollow central portion;
- and
- an upper mold and a lower mold for manufacturing hollow parts, wherein the fiber spun from the nozzle wound or weaved along inner shapes of the inner surfaces of the upper mold and the lower mold,
- wherein the fiber is impregnated with a resin prior to the spinning by the nozzle, and
- wherein the nozzle is coupled with the spinning unit with a degree of freedom of a first level or a second level, and tilted toward a first shaft or a second shaft at an end of the spinning unit.
