Abstract

Disclosed are a partition panel for vehicles and a method of manufacturing the same. The method includes mounting a first prepreg formed to have a shape corresponding to a molding groove on a lower die provided with the molding groove. The molding groove is inclined upwards from the center of a lower portion of the lower die to opposite ends of the lower die. A second prepreg having a sheet type is mounted on the lower die so as to cover the first prepreg. The first prepreg and the second prepreg are integrally molded by placing an upper die on the lower die.

First claim

What is claimed is:

1. A method of manufacturing a partition panel of a vehicle, the method comprising:
mounting a first prepreg formed to have a shape corresponding to a molding groove on a lower die provided with the molding groove, the molding groove inclined upwards from the center of a lower portion of the lower die to opposite ends of the lower die;
mounting a second prepreg having a sheet type on the lower die so as to cover the first prepreg; and
integrally molding the first prepreg and the second prepreg by placing an upper die on the lower die;
wherein the first prepreg includes a first tape mounted at a first portion of the molding groove inclined upwards from the center of the lower portion thereof to one end of the lower die and a second tape mounted at a second portion of the molding groove inclined upwards from the center of the lower portion to an opposite end of the lower die; and
wherein mounting the first prepreg and the second prepreg on the lower die comprises mounting the first tape in the molding groove and then mounting the second tape in the molding groove so as to intersect the first tape at the center of the lower portion of the molding groove.

2. The method according to claim 1 , wherein the first tape and the second tape have substantially the same shape.

3. The method according to claim 2 , wherein the first tape and the second tape are formed from one rectangular prepreg sheet.

4. The method according to claim 1 , wherein the molding groove is bilaterally symmetrical.

5. The method according to claim 1 , wherein, in mounting the first prepreg and the second prepreg on the lower die, a designated surface of the second tape corresponding to a designated surface of the first tape contacting the lower die faces the upper die.

6. The method according to claim 1 , wherein:
the first tape and the second tape have substantially the same shape;
the molding groove is bilaterally symmetrical; and
in mounting the first prepreg and the second prepreg on the lower die, a designated surface of the second tape corresponding to a designated surface of the first tape contacting the lower die faces the upper die.

7. The method according to claim 1 , further comprising, after integrally molding of the first prepreg and the second prepreg, ejecting the integrally molded first prepreg and second prepreg from the upper and lower dies and then trimming unnecessary portions of the first prepreg and the second prepreg.

8. The method of claim 1 , wherein the first prepreg and the second prepreg are formed to have a multilayer structure having a plurality of reinforced fiber layers.

9. The method of claim 8 , wherein the plurality of reinforced fiber layers is stacked in a designated arrangement direction.

10. The method of claim 8 , wherein the plurality of reinforced fiber layers are formed as a woven fabric.

11. The method of claim 1 , wherein the first prepreg includes reinforced fibers preliminarily impregnated with a resin, the reinforced fibers comprising fibers selected from the group consisting of carbon fibers, glass fibers, aramid fibers and natural fibers.

12. The method of claim 1 , wherein the first prepreg includes reinforced fibers preliminarily impregnated with a thermosetting resin or a thermoplastic resin.

13. The method of claim 12 , wherein the resin comprises a resin selected from the group consisting of polypropylene, polyethylene, and polyurethane.

14. A method of manufacturing a partition panel of a vehicle, the method comprising:
mounting a first prepreg formed to have a shape corresponding to a molding groove on a lower die provided with the molding groove, the molding groove inclined upwards from the center of a lower portion of the lower die to opposite ends of the lower die;
mounting a second prepreg having a sheet type on the lower die so as to cover the first prepreg; and
integrally molding the first prepreg and the second prepreg by placing an upper die on the lower die;
wherein after manufacture the partition panel comprises:
a panel part formed of a composite material to divide a trunk and the inside of the vehicle from each other, the panel part having a first end and a laterally spaced second end; and
a reinforcement part formed of a composite material, inclined upwards from the center of a lower portion of the panel part toward the first and second ends of the panel part, the reinforcement part being connected integrally to the panel part, the composite material of the panel part and the composite material of the reinforcement part being formed from the first prepreg and the second prepreg.

15. The method according to claim 14 , wherein the reinforcement part includes:
a main body region connected to the center of the lower portion of the panel part;
a first deployment region extending from the main body region so as to be inclined upwards toward the first end of the panel part; and
a second deployment region extending from the main body region so as to be inclined upwards toward the second end of the panel part;
wherein connection parts between the first and second deployment regions and the first and second ends of the main body region are configured such that the connection parts each have a width that gradually decreases in a downward direction and then increases.

16. The method according to claim 14 , wherein the reinforcement part includes:
a first reinforcement tape-shaped portion connected to a portion of the panel part inclined upwards from the center of the lower portion of the panel part to a first end of the panel part; and
a second reinforcement tape-shaped portion overlapping the first reinforcement tape-shaped portion at the center of the lower portion of the panel part and connected to a portion of the panel part inclined upwards from the center of the lower portion of the panel part to a second end of the panel part.

17. The method according to claim 16 , wherein the first tape and the second tape have substantially the same shape.

18. The method according to claim 16 , wherein the molding groove is bilaterally symmetrical.

19. The method according to claim 14 , further comprising, after integrally molding of the first prepreg and the second prepreg, ejecting the integrally molded first prepreg and second prepreg from the upper and lower dies and then trimming unnecessary portions of the first prepreg and the second prepreg.

20. The method of claim 14 , wherein the first prepreg and the second prepreg are formed to have a multilayer structure having a plurality of reinforced fiber layers.
