Description
Die Erfindung betrifft ein Verfahren zum Herstellen einer TFP-Preform bestehend aus einer im Zick-Zack-Stich mit einem Nähfaden auf einem Untergrund vernähten Verstärkungsfaser gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a method for producing a TFP preform consisting of a zig-zag stitch with a sewing thread on sewed to a substrate reinforcing fiber according to the generic term of claim 1
TFP-Preforms (Tailor Fiber Placement) entstehen durch Aufnähen von Verstärkungsfasern auf einem Untergrund. Die bisher für die Herstellung von TFP-Preforms bekannten Verfahren mit Stickautomaten oder Zick-Zack-Nähmaschinen eignen sich nur zur Herstellung von ebenflächigen TFP-Preforms.TFP preforms (Tailor Fiber Placement) are created by sewing on reinforcing fibers on a surface. The hitherto for the production of TFP preforms known methods with embroidery machines or zig-zag sewing machines are only suitable for the production of planar TFP preforms.

Der Erfindung liegt die Aufgabe zugrunde ein Verfahren zur Herstellung einer dreidimensional geformten TFP-Preform zu schaffen.Of the Invention is based on a process for the preparation of the object to create a three-dimensionally shaped TFP preform.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.These The object is achieved by a Method solved with the features of claim 1. further developments The invention are specified in the subclaims.
Die Erfindung ist durch einen Aufbau der TFP-Preform auf einem Schaumstoffkern mittels eines Tufting-Nähverfahrens gekennzeichnet. Dazu werden die abgelegten Verstärkungsfasern mittels eines Nähfadens im Zick-Zack-Stich auf den Schaumstoffkern aufgetuftet. Nachdem die fertig aufgenähte TFP-Preform mittels eines schmelzenden und aushärtenden Binders fixiert ist, kann sie vom Schaumstoffkern abgezogen werden.The Invention is by a construction of the TFP preform on a foam core by means of a tufting sewing method characterized. For this purpose, the deposited reinforcing fibers by means of a sewing thread in a zigzag stitch tufted on the foam core. After this the finished sewn-on TFP preform is fixed by means of a melting and hardening binder, it can be removed from the foam core.
Mit dem erfindungsgemäßen Verfahren steht ein neues, sehr vielseitiges Fertigungsverfahren für die Herstellung von dreidimensionalen, textilen Preforms zur Verfügung. Die TFP-Preforms lassen sich mit dem erfindungsgemäßen Verfahren rechnergesteuert herstellen und mit partiellen Verstärkungen für inhomogene Kraftflüsse versehen. Sie bieten den Vorteil des extrem hohen Leichtbaupotentials von TFP-Aufbauten.With the method according to the invention represents a new, very versatile manufacturing process for the production of three-dimensional, textile preforms available. The Leave TFP preforms with the inventive method computer-controlled and with partial reinforcements for inhomogeneous power flows Mistake. They offer the advantage of extremely high lightweight potential of TFP bodies.
