What is claimed is: 1. A method for producing composite materials comprising a Cu-based amorphous alloy and high fusion point element(s) comprising: (a) melting high fusion point element(s) selected from a group consisting of Ta and W together with Zr as a matrix element, to produce a binary master alloy; and (b) remelting the binary alloy obtained from the step (a) together with Cu, Zr and Ti as matrix element(s), to produce another master alloy with target composition. 2. The method for producing composite materials comprising a Cu-based amorphous alloy and high fusion point element(s) as claimed in claim 1, wherein the target composition of the master alloy in the step (b) satisfies the following Chemical formula 1; CuaZrbTicRd [Chemical formula 1] where R is Ta, W or combination thereof, a, b, c and d are atomic weight ratio, a+b+c+d equals 100, a, b, c and d have the range of 45≦a≦65, 10≦b≦35, 5≦c≦30 and 5≦d≦10, respectively. 3. The method for producing Cu-based amorphous matrix composite materials containing high fusion point element as claimed in claim 1 further comprising: (c) melting the master alloy of the step (b) in the atmosphere of Ar in a Quartz tube using a radio-frequency melting furnace; and (d) injecting the melted alloy of the step (c) into a molding die with blowing Ar gas, and solidifying the same.
