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.

Apparatus for manufacturing a high-strength composite sheet having superior embeddability, and method for manufacturing a high-strength composite sheet using the same

Provided is a method of preparing thermoplastics-continuous fiber hybrid composite, which is easily woven and has excellent uniformity and impregnation at the time of hot melt impregnation after the weaving, including: a) widely and uniformly stretching a bundle of glass fibers; b) heating the stretched glass fibers; c) preparing a thermoplastics-continuous fiber bonding material by binding the heated glass fiber with thermoplastics; d) preparing a multi-layered thermoplastics-continuous fiber bonding material by folding the bonding material in a shape of zigzag; and e) pressing the multi-layered thermoplastics-continuous fiber bonding material.
