Abstract
Official abstract text for this publication.
A method is provided for the preparation of a semifinished product made of fiber material with an upper side and with an underside prior to a wet-pressing process. The method includes following steps: arrangement of a semifinished product made of fiber material with the underside on a preparation area with a large number of suction apertures, application of a reduced pressure to the underside of the semifinished product by way of the suction apertures, and introduction of a flowable matrix material by way of the upper side of the semifinished product.
