Method for producing preforms from fiber composites as well as preform produced with this method

A method for producing preforms from fiber composite semi-finished products and polymer so as to use them as components after a curing process comprising:

• alternately placing layers of cut dry fiber composite semi-finished product sections and polymer layers with a predetermined shape on top of each other to initially form a bonded fabric on a working surface,
• forming individual profile parts of said bonded fabric and subsequently curing the individual profile parts to form a specified preform from the bonded fabric,
• wherein the polymer layers exhibit shapes that ensure bonding of inner cut semi-finished product sections as well as of cut semi-finished product sections that form outer sides of the preform facing each other in overlapping areas, and
• wherein the polymer layers contain local recesses in order to minimize shearing stress between the semi-finished product sections in areas of the local recesses when forming the individual profile parts of the bonded fabric.
