Method for producing a moldable, thermoplastic, continuous fiber reinforced composite structure, moldable composite structure, and device for producing same
The invention is characterized by a semifinished composite structure product with the at least two layers, of which the at least one layer, in which the continuous fibers are contained, is heated such that the matrix of thermoplastic material is heated within at least one first surface region to or above a melting temperature that can be assigned to the thermoplastic material, and the matrix of thermoplastic material is kept to a temperature below the melting temperature within a second surface region directly adjoining the first surface region. The semifinished composite structure product is heated in this way so that the moldable thermoplastic, continuous fiber-reinforced composite structure in which the continuous fibers within the first surface region are movable relative to each other and those within the second surface region are spatially fixed relative to each other.
