Abstract

A manufacturing method of a long fiber composite material according to an exemplary embodiment of the present invention includes: preparing a main body where inlets and outlets through which a plurality of fiber bundles are respectively charged into and discharged from are formed; adjusting a height of a plurality of first through-hole plates and a height of a second through-hole plate that are disposed in the main body to be the same; having the plurality of fiber bundles penetrated through the first through-hole plate and the second through-hole plate; and adjusting the height of the first through-hole plate and the height of the second through-hole plate to be different from each other after penetrating the plurality of fiber bundles through the first through-hole plate and the second through-hole plate.

First claim

What is claimed is:

1. A manufacturing method of a fiber composite material, comprising:
preparing a main body where inlets and outlets through which a plurality of fiber bundles are respectively charged into and discharged from are formed;
adjusting a height of a plurality of first through-hole plates and a height of a second through-hole plate that are disposed in the main body to be the same;
having the plurality of fiber bundles penetrated through the first through-hole plate and the second through-hole plate; and
adjusting the height of the plurality of first through-hole plates and the height of the second through-hole plate to be different from each other after the plurality of fiber bundles penetrate through the plurality of first through-hole plates and the second through-hole plate,
wherein a second hole through which the plurality of fiber bundles are penetrated is provided in the second through-hole plate, and has a predetermined length, and
wherein a plurality of protrusions are formed only in an inner wall of the second hole, and arranged along a length direction of the second hole,
wherein the second through-hole plate is disposed between a pair of first through-hole plates that are adjacent to each other among the plurality of first through-hole plates.

2. The manufacturing method of the fiber composite material of claim 1 , after the adjusting of the height of the first through-hole plate and the height of the second through-hole plate to be different from each other, further comprising moving the plurality of fiber bundles in a direction of the outlet from the inlet.

3. The manufacturing method of the fiber composite material of claim 1 , wherein in the adjusting of the heights of the first and second through-hole plates, the plurality of fiber bundles that penetrate the first through-hole plate and the second through-hole plate are adjusted to a straight line.

4. The manufacturing method of the fiber composite material of claim 1 , wherein, in the adjusting of the heights of the first and second through-hole plates, the second through-hole plate is disposed at a height that is lower than that of the first through-hole plate.

5. The manufacturing method of the fiber composite material of claim 1 , wherein, in the adjusting of the heights of the first and second through-hole plates, the second through-hole plate is disposed at a height that is higher than that of the first through-hole plate.

6. The manufacturing method of the fiber composite material of claim 1 , wherein the plurality of first through-hole plates are disposed in parallel with each other along a first direction in the main body, and a plurality of first holes through which the plurality of fiber bundles are formed in the respective first through-hole plates.

7. The manufacturing method of the fiber composite material of claim 6 , wherein the plurality of first holes have circular-shaped cross-sections.

8. The manufacturing method of the fiber composite material of claim 6 , wherein the plurality of fiber bundles penetrated through the first through-hole plate penetrate the second through-hole plate.

9. The manufacturing method of the fiber composite material of claim 1 , wherein the plurality of protrusions have curved shapes.

10. The manufacturing method of the fiber composite material of claim 1 , wherein the second hole is provided in plural.

11. The manufacturing method of the fiber composite material of claim 1 , wherein the second through-hole plate is provided in plural.
