Embodiment Construction

[0093] Hereinafter, the same reference numerals in the drawings denote the same or similar components.

[0094] In the following, reference will be made to Figure 1a to Figure 1d , Figure 2a to Figure 2c and Figure 3a to Figure 3c A first example of a method for manufacturing a workpiece made of a fiber composite material will be described.

[0095] The first blank mold 1 in Figure 1a and Figure 1b Shown in side view and plan view. The materials used to manufacture the desired workpiece, namely the primary material 6 mentioned below for the first region 4 and the secondary material 7 for the second region 5, are used on the surface 2 of the film 3, which Used as a support device. The entire surface 2 of the film 3 is preferably covered by the first region 4 and the second region 5 .

[0096] The main material 6 is preferably a pre-impregnated fiber semi-finished product (prepreg), for example with fibers made of carbon. The pre-impregnated fiber semi-finished prod...

Abstract

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.

Description

Technical field [0001] The invention involves a manufacturing method of a workpiece composed of fibrous composite materials and a corresponding device that can be implemented in accordance with the manufacturing method of the present invention. [0002] In the following, although the present invention is based on the manufacturing of the load -bearing structure in the aircraft, the present invention is not limited to this, but to generally involve workpieces composed of fibrous composite materials, especially slender workpieces, especially slender workpiecesmanufacture. Background technique [0003] The high stretch strength and low weight of the fibrous composite material have been proven in the field of aircraft manufacturing.Except for the flat parts in the shell, slender parts, such as the so -called longitudinal beams, are formed by fibrous composite materials.The longitudinal beams with the same cross-section can be made by continuous flow. [0004] The vertical beams with...
