Disclosed is a method for producing components from fiber-reinforced thermoplastic on the basis of fiber tapes impregnated with matrix material. The method includes manufacturing a multitude of semi-finished products, each of which has a plurality of non-consolidated layers of fiber tapes. The semi-finished products are placed in a consolidation device in such a way that the semi-finished products are in direct contact with one another. The semi-finished products are then consolidated using the consolidation device and the semi-finished products are at least partially joined to one another during the consolidation process. The joined semi-finished products are then cut apart using a cutting device.

20170334150 · 2017-11-23 · ·

Resin infusing a composite preform includes locating the preform on an upper tool surface having a resin reservoir element on a downstream side of the composite preform. A vacuum bagging film is placed over the tool surface to cover the composite preform and the resin reservoir element, and is sealed relative to the tool surface to define a sealed resin infusion chamber. A resin supply is provided along with a resin flow path from the resin supply to the resin infusion chamber on an upstream side of the composite preform, through the composite preform and through the reservoir inlet to the resin reservoir. At least partial vacuum pressure applied to the reservoir outlet establishes a pressure differential between the resin supply and reservoir outlet to drive resin from the resin supply through the resin flow path, infusing the composite preform with resin and collecting excess resin in the resin reservoir.

Method for producing thermosetting composite parts by drape forming of preimpregnated material

A process for fabricating a partially polymerized prepreg material. Fibers are impregnated with thermosetting resin. The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by drape forming of the prepreg material.
