Abstract

A manufacturing apparatus of a long fiber composite material according to an exemplary embodiment of the present invention includes: a main body where an inlet through which a plurality of fiber bundles are penetrated is formed at one side and an outlet through the fiber bundles are discharged is formed at the other side; a plurality of first through-hole plates that are arranged in parallel with each other along a first direction in the main body and having a plurality of through-holes through which the plurality of fiber bundles are penetrated formed therein; and a second through-hole plate that is disposed between a pair of first through-hole plates that are adjacent to each other among the plurality of first through-hole plates, and through which the plurality of fiber bundles penetrated through the first through-hole plates are penetrated.

First claim

What is claimed is:

1. A manufacturing apparatus of a long fiber composite material, comprising:
a main body where an inlet through which a plurality of fiber bundles are penetrated is formed at one side and an outlet through the fiber bundles are discharged is formed at the other side;
a plurality of first through-hole plates that are arranged in parallel with each other along a first direction in the main body and having a plurality of through-holes through which the plurality of fiber bundles are penetrated formed therein; and
a second through-hole plate that is disposed between a pair of first through-hole plates that are adjacent to each other among the plurality of first through-hole plates, and through which the plurality of fiber bundles penetrated through the first through-hole plates are penetrated,
wherein long holes through which the plurality of fiber bundles are penetrated are provided in the second through-hole plate, and
wherein a plurality of protrusions are formed in an inner wall of each long hole.

2. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein the plurality of protrusions have curved shapes.

3. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein the long hole is provided in plural.

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

5. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein the second through-hole plate is movable in a second direction that is perpendicular to the first direction.

6. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein a gap between a pair of first through-hole plates that are adjacent to each other among the plurality of first through-hole plates is adjustable.

7. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein the plurality of through-holes have circular-shaped cross-sections.

8. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein the inlet is provided in plural.

9. The manufacturing apparatus of the long fiber composite material of claim 8 , wherein the plurality of fiber bundles are respectively injected into the plurality of inlets.

10. The manufacturing apparatus of the long fiber composite material of claim 1 , wherein a space is formed in the main body.

11. The manufacturing apparatus of the long fiber composite material of claim 10 , wherein a resin that is coated to fiber filaments that form the fiber bundle is stored in the space of the main body.
