Problems solved by technology

[0006] During the manufacture of sandwich elements according to the method briefly described above, there is the disadvantage that only one type of matrix material (in terms of composition and applied thickness) can be applied to the outermost cladding layer
Also, depending on the viscosity of the matrix material and the permeability of the cover layer, the matrix material may penetrate too deeply into the cover layer and penetrate the core layer in an unchecked manner

Embodiment Construction

[0042] figure 1 and figure 2 shows a sandwich member 1 according to the invention before pressurization ( figure 1 ) and after pressurization ( figure 2 ) schematic diagram.

[0043] figure 1 The sandwich component 1 shown schematically in has a core layer 2 and three fiber layers 3 . The fiber layer 3 is arranged on top of the core layer 2 .

[0044] A matrix material 4 is applied to each of the three fiber layers 3, wherein the matrix material 4 is likewise arranged between the innermost fiber layer 6 and the core layer 2, the matrix material 4 is applied to the innermost Below the fiber layer 6.

[0045] In terms of the amount of matrix material 4 applied, for example, more matrix material 4 has been applied on top of the innermost fiber layer 6 than on top of the outermost fiber layer 5 .

[0046] Thus, the matrix material 4 has been applied "differently" (in the case of the present illustrative example embodiment in different amounts) to the innermost fiber layer...

Abstract

The invention discloses a sandwich component. The sandwich component (1) comprises at least one core layer (2) and at least two fiber layers (3), wherein at least one matrix material (4) is applied to at least one of said fiber layers (3) and / or or below, wherein the matrix material (4) is applied in different ways to at least two of the fiber layers (3) and / or the matrix material (4) is applied in different ways along the top of the fiber layers (3) and / or below are applied to at least one of said fiber layers (3).

Description

technical field [0001] The invention relates to a sandwich component, in particular for use in the automotive industry. Background technique [0002] A sandwich component should generally be understood to mean a component made of multiple layers of the same material or of different materials. In the simplest case, the sandwich component consists of two covering layers, an upper covering layer and a lower covering layer, and a core layer arranged between the upper covering layer and the lower covering layer. The cover layer is constructed in the form of fibers and / or textiles and can be penetrated by the adhesive-like matrix material. The final connection between the layers is often done by applying pressure by means of a suitable tool, such as a press. [0003] Such sandwich components are used in many different fields. In recent years, however, their importance, especially as structural components in the field of lightweight vehicle construction, has increased considerab...
