Definitions
- the invention relates to a method according to the preamble of claim 1 for producing a composite component for a wind energy plant, comprising a plurality of at least two-component composite moldings, wherein a first component of a forming core material and a second component is formed as part of a joining layer.
- the invention also relates to a corresponding composite component according to the preamble of claim 9.
- the invention relates in particular to a sandwich component, a rotor blade element and a wind turbine with such a composite component.
- Composite moldings are moldings made of two or more interconnected materials that are manufactured as solids of fixed geometrical dimensions. The materials occurring in the composite usually have functional properties, in particular earmarked with regard to their field of application.
- the properties of the material obtained are material and possibly also geometric properties of the individual components of importance. This makes it possible to combine properties of different components with each other, whereby the composite materials find wide applications.
- the properties required for the final product can be adjusted as needed by choosing different starting materials for the components.
- a composite component usually has properties that represent an optimized behavior of the composite molded part under load.
- the properties may be related to, for example, a certain strength, rigidity or elasticity.
- a composite molded article should represent an optimized behavior of the composite compared to a single component of the composite.
- the development of composite molded parts is basically that the required properties are optimized in combination to the lifetime in order to withstand a long-term load.
- high and widely varying load effects are exerted which, in addition, increase with an increasing part of a wind energy plant.
- rotor blades should withstand the static as well as the occurring dynamic loads.
- Composite components can be manufactured in different ways.
- rotor blades of a wind turbine today are mainly made of fiber composites, in the reinforcing fibers, usually as a mat, are embedded in a matrix, usually glass fiber reinforced plastic.
- a rotor blade is usually produced in a half-shell sandwich construction.
- Carbon fiber reinforced plastic used.
- the properties required here are on the one hand a low weight with relatively high structural strength, as well as different degrees of hardness and a tensile strength oriented on the load effect.
- Glass fiber reinforced or carbon fiber reinforced materials could, at least in principle and under the above aspects, replace the previous use of balsa wood with regard to its optimized strength.
- the typical use of composite components is to integrate them into a sandwich construction; In this case, several layers are embedded with different properties in order to obtain a correspondingly adjusted component.
- the core material can consist of materials such as paper, cardboard, plastics, metals, balsa wood, corrugated iron, plastics, foams and other shaping components, usually associated with constructive cavities.
- the task of the core material is to transmit tensile forces as well as shear forces and to support the surface layers.
