Abstract

The object of the present invention is a layered semi-finished product having a layer sequence containing at least one layer of an unconsolidated fabric of reinforcing fibers. At reduced pressure, this layer sequence is arranged between a top and a bottom film connected to each other along their periphery in a pressure-retaining manner. In advantageous modifications of the layered semi-finished product according to the invention, the preforming of the semi-finished, as well as the inclusion of metallic inserts or other components into said semi-finished is intended. Furthermore, a method for producing the layered semi-finished product according to the invention is described.
