Abstract

The invention provides a method for producing a component (37) for aerospace, with the following method steps: supplying a lay-up arrangement (1) to be laid by means of a tape-laying machine (25), with a glass-fiber lay-up (8), which is preimpregnated with a resin matrix (10), and/or supplying a structural arrangement (12) to be laid by means of a tape-laying machine (25), with a structure (16) which is made of metal and is preimpregnated with a resin matrix (18), laying the lay-up and/or structural arrangement (1; 12) on a laminating apparatus (23) by means of a tape-laying machine (25), and curing the lay-up and/or structural arrangement (1; 12) and therefore forming the component (37).

Claims

1. Method for producing a component for the aerospace industry, comprising:

supplying a structural arrangement comprising a structure which is made of metal and is pre-impregnated with a resin matrix, the structure being formed as a metal net having diamond-shaped, rectangular and/or honeycomb-shaped recesses filled with the resin matrix, and wherein the metal net comprises a fixed and defined structure;

laying the structural arrangement on a laminating apparatus by a tape-laying machine, wherein the structural arrangement is laid along different directions with respect to the laminating apparatus; and

curing the structural arrangement to form the component.

2. Method according to claim 1, wherein the tape-laying machine is moved along two or three axes.

3. Method according to claim 1, wherein a plurality of structural arrangements are laid in layers one above another.

4. Method according to claim 1, wherein at least one layer of CFRP prepreg material is laid on, between or below the structural arrangement.

5. Method according to claim 1, wherein the structural arrangement is supplied to the tape-laying machine by a feeding device.

6. Method according to claim 1, wherein the structural arrangement is supplied as a coiled web material.
