Disclosed is a method for manufacturing a high-strength composite sheet, in which a peroxide-containing polymer film is used to allow uniform molecular weight distribution and improved embeddability. The method includes: attaching a peroxide-containing polymer film to one or both sides of a reinforcement material; pressing the peroxide-containing polymer film using a heating press such that the peroxide-containing polymer film is embedded into the reinforcement material, to thereby form a composite film; and cooling the pressed composite film using a cooling press.

1. A method of manufacturing a high-strength composite sheet, the method comprising: attaching a peroxide-containing polymer film to at least one side of a reinforcement material;pressing the peroxide-containing polymer film using a heating press such that the peroxide-containing polymer film is embedded into the reinforcement material, to thereby form a composite film; andcooling the pressed composite film using a cooling press,wherein the peroxide-containing polymer film comprises at least one peroxide selected from the group consisting of 3,6,6,9,9 pentamethyl-3n-propyl-1,2,4,5 tetraoxacyclononane and 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane,wherein the peroxide-containing polymer film further comprises the peroxide in an amount of greater than 2 parts by weight and at most 4 parts by weight, based on 100 parts by weight of the peroxide-containing polymer film, andwherein a bundle of fibers in the reinforcement material has a density ranging from 600 tex to 1200 tex. 2. The method according to claim 1, wherein the reinforcement material comprises organic or inorganic fibers, which include at least one selected from the group consisting of glass fibers, carbon fibers, basalt fibers, and aramid fibers. 3. The method according to claim 2, wherein the reinforcement material has an average fiber diameter ranging from 10 μm to 20 μm. 4. The method according to claim 1, wherein the peroxide-containing polymer film comprises thermoplastic or thermosetting resins, which include at least one selected from the group consisting of thermoplastic or thermosetting resins including polypropylene, polyethylene, polyester, polyamide, and acrylonitrile butadiene styrene (ABS) copolymers. 5. The method according to claim 4, wherein the thermoplastic resin has a melt index (MFI) of 1 to 100 g/10 min. 6. The method according to claim 4, wherein the peroxide-containing polymer film further comprises at least one kind of additive selected from among pigments, thermal stabilizers, UV stabilizers, or viscosity controlling agents. 7. The method according to claim 6, wherein the peroxide-containing polymer film comprises greater than 2 parts by weight and at most 4 parts by weight of the viscosity controlling agent and 0.1 to 10 parts by weight of the other additives, based on 100 parts by weight of the polymer film, the viscosity controlling agent containing peroxide. 8. The method according to claim 1, wherein the reinforcement material is present in an amount of 20 parts by weight to 80 parts by weight based on 100 parts by weight of the composite film. 9. The method according to claim 1, wherein the composite film further comprises a release film attached to an outer side of the peroxide-containing polymer film. 10. The method according to claim 1, wherein the heating press is configured to attach two peroxide-containing polymer films to a same side of the reinforcement material. 11. The method according to claim 1, wherein the reinforcement material comprises basalt fibers. 12. The method according to claim 1, wherein the peroxide-containing polymer film further comprises 2,5-dimethyl-2,5-bis(t-butylperoxy)hexane. 13. The method according to claim 1, wherein the peroxide-containing polymer film comprises acrylonitrile butadiene styrene (ABS) copolymers. 14. The method according to claim 4, wherein the peroxide-containing polymer film further comprises UV stabilizers.
