Abstract:
1. A method for producing three-dimensional molded parts made of fiber material under the use of a mold comprising a bottom mold, whose inner side defines the contours of the bottom side of the molded part, and at least one top mold, whose inner side defines the contours of the top side of the molded part, with at least one of the bottom mold and the top mold featuring holes for the passage of air, said method comprising: blowing-in of fibers by an air current into the intermediate space between the bottom mold and a temporary auxiliary top mold; depositing fibers on the inner sides of the bottom mold and the temporary auxiliary top mold until the mold is filled, whereby a preform is formed from fiber material; removing the temporary auxiliary top mold; placing the top mold, whereby the preform is compacted; and connecting the fibers by a mixed-in bonding agent whereby the preform is solidified into a molded part.
