Abstract (en)

[origin: WO2020070204A2] The invention relates to methods for producing a structural component (B). The methods comprises in each case the provision of a preformed layer structure (100) having a plurality of layers (110), which each have reinforcing fibers (21) embedded in a thermoplastic matrix material (20), the heating of the layer structure (100) in a cavity (205) formed between a contour surface (150a) and a contact part (220) to a first temperature which is greater than a melting point of the thermoplastic matrix material (20), and, by applying a compression pressure, the cooling of the layer structure (100) in the cavity (205) to a solidification temperature which is, for example, smaller than the melting point of the thermoplastic matrix material (20). According to a method, the compression pressure is generated in that a magnetic field directed transversely to the contour surface (150a) is generated by means of a magnet device (240), which magnetic field contracts or compresses the contact part (220) and the contour surface (150a) relative to one another. According to a further method, inductive heating of the cavity (205) occurs.
