Problems solved by technology

It is problematic in fiber-reinforced composite components that cracks of the corresponding fibers can form in the load-bearing regions of the component; this crack formation can initially occur due to bending moments caused by increased dynamic mechanical loads

Embodiment Construction

[0074] In Figure 1 to Figure 4 In , for the same or similar components or components with the same or similar functions, the same reference numerals are used for the sake of simplicity.

[0075] FIG. 1 shows a composite molded part 1 , which is depicted as a shaped core material 2A in the form of a cuboid. In this case, the braid 20 , in this case a braid mat of glass fibers which is closed as a cuboid jacket, surrounds the cuboid and shows the fibers oriented at a functional fiber angle α of 45° to one another. The individual fibers 21 and 22 here show a fiber angle of α=45° and form a functional force parallelogram on the surface, said force parallelogram with respect to figure 2 Elaborate. Here, a uniform distribution of the fibers is provided in this view. However, it is also conceivable (eg depending on the load distribution) that the fibers 21 , 22 expand differently. A functional orientation in a locally tighter weave can therefore also occur in regions where high...

Abstract

The invention relates to a composite molded part (1), in particular produced in accordance with a method according to the invention, in particular for a wind turbine, comprising: a thermoplastic plastic and a fiber composite semi-finished product. Furthermore, according to the invention, the fiber composite semi-finished product comprises a flexible, braided-structure-like fiber system (20), and the thermoplastic plastic is distributed as a shaping core material (2A) in the flexible, braided-structure-like fiber system (20) of the fiber composite semi-finished product and is connected to the braided-structure-like fiber system (20), wherein the braided-structure-like fiber system (20) in the composite with the shaping core material (2A) has fibers (21, 22) oriented with respect to each other in such a way that the fibers cross each other, said fibers having a fiber angle at a crossing point which is between 10 degrees and 90 degrees, in particular between 30 degrees and 60 degrees, the fibers (21, 22) preferably being oriented with respect to each other at a fiber angle of about 45 degrees with a variance range of + / -5 degrees, and wherein in the composite the braided-structure-like fiber system (20) forms the outer functional layer of the composite molded part.

Description

technical field [0001] A method according to the preamble of claim 1 for producing composite molded parts, in particular composite molded parts for wind energy installations, comprising a thermoplastic and a fiber composite semi-finished product. The invention also relates to a composite molded part, a sandwich component, a rotor blade element and a wind energy installation. Background technique [0002] A composite molded part is a molded part made of two or more materials connected to one another, which is produced as a body with fixed geometrical dimensions. The materials present in composite parts often have functional properties that are especially restricted by their field of use. The material properties and possibly also the geometrical properties of the individual components are of importance for the properties of the material obtained. This makes it possible to combine the properties of the different components with one another, whereby the composite material has ...
