Abstract:
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; and cooling 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, and wherein a bundle of fibers in the reinforcement material has a density ranging from 600 tex to 1200 tex.
