Disclosed is an infusion method for the manufacture of a fibre-reinforced composite component with semi-finished textile products in an open moulding tool, in which at least one local gas reception space is designed for the reception of volatile substances, such as resin gases and residual air contained in the matrix material and/or in the system, which gas reception space is blocked off from the matrix material by a local semi-permeable membrane; also disclosed is a system for the execution of such a method.

The present invention provides a tool for the production of fiber composite components. The tool has a surface for depositing semifinished fiber products on the surface, the surface having a number of openings for feeding a matrix to the deposited semifinished fiber products. It is consequently possible to dispense entirely or partly with a conventional flow promoter and possible to achieve a high quality of fiber composite component.

The present invention provides a structural element, in particular for an aircraft or spacecraft, comprising a core, the material density of which varies, at least in portions, in order to optimise the natural vibration behaviour of the structural element. The present invention further provides a method for producing a structural element, in particular for an aircraft or spacecraft, comprising the following steps: providing a structural element which has a core; determining the natural vibration behaviour of the structural element; and varying the material density of the core of the structural element, at least in portions, in such a way that the natural vibration behaviour of the structural element is optimised. The present invention provides still further an aircraft or spacecraft and a rotor blade, in particular for a wind turbine, comprising such a structural element.

Disclosed is a reinforcing material for the local reinforcement of a component formed with a composite material, in particular in areas of force introduction and/or connecting areas. The reinforcing material is formed by a metallic sheet-like formation, the metallic sheet-like formation having a surface with increased roughness to improve adhesion and a coating applied to the surface to provide a seal and improve the bond with the composite material. As a result of the presence of a coating on the metallic sheet-like formation, once it has been rolled up on supply rolls, said sheet-like formation can be drawn off from the supply rolls and at the same time processed in an automated manner by means of known computer-controlled laying devices with CRP prepreg materials in web form by laying layer by layer to produce components, in particular of large format, for aircraft. The reinforcing material thereby ensures a high embedding strength in the case of introduced boreholes or the like, in particular in areas of force introduction and/or connecting areas. Also disclosed is a method for producing a reinforcing material. In addition, the invention relates to a method for producing components, in particular components of large format for aircraft, with the composite material and with the reinforcing material.

The invention relates to a rod-shaped fiber composite material (400) composed of a matrix (412) and a circular braid (402) embedded into the matrix. To increase the stability of the fiber composite material (400) and also to perform ducting functions for electricity and fluids, the wall of the circular braid is provided with wall chambers (408) which are separated by a phase boundary from the matrix (412) of the fiber composite material (400). These wall chambers (408) lead to inner and outer sections of the wall of the circular braid (402) being spaced apart, which is useful for the stability with regard to flexing and torsional loading in particular. Rod-shaped fiber composite materials (400) according to the invention can be used for creating stable structural components as well as for producing efficiently protected ducts. The invention further relates to an apparatus and a process which are useful for producing fiber composite material according to the invention.
