Abstract

A method for producing a three-dimensional preform from reinforcing fibers for producing a component from a fiber-reinforced plastic comprises the steps of introducing at least one layer of fibers having a binder into a draping mold, forming the at least one layer of fibers by at least one forming element which is displaceable along the draping mold, applying an airtight film to the at least one layer of fibers during or directly after the forming, creating a negative pressure in the intermediate space between the airtight film and the draping mold, activating the binder and removing the negative pressure after curing of the binder.
