The present invention relates to a method for manufacturing a workpiece 15 which is manufactured by fiber composite material, wherein the method comprises the following steps: providing at least one supporting device 3; using one main material 6 which is formed by presoaked fiber half-finished product and/or one secondary material for at least one supporting device 3 for forming at least two blank mould areas 1 and 10 with a mode that at least one selected from at least two blank mould areas 1 and 10 has the main material and at least one the blank mould area has the secondary material. The blank mould areas 1 and 10 extrude with each other with a mode for forming the workpiece blank 14 so that at least one supporting device 3 is installed on the surface of workpiece blank 14. At least one supporting device 3 and the secondary material 7 are removed from the workpiece blank 14 for forming the workpiece 15.
