Tailored Reinforcements

Draping Two-dimensional tailored reinforcements (TRs) are formed to a 3D geometry using draping aids in preform molds.

Structural seams. The purpose of this seam type is to stitch the elements, which transmit the forces between various semi-finished goods or layers via tailored reinforcements e.g., ribs on support structures). These seams can also be used for positioning inserts or to enhance connections of inserts to the entire structure. Joining seams penetrate through the complete preform and are stitched by using threads made of carbon or glass fibers. 

The most important innovation is the introduction of a preparatory production step, called tailored reinforcement (TR). All of the required elements are integrated into the preform by means of a special stitching type, e.g., structural 3D or TT (through the thickness) reinforcement, load-bearing elements, etc ...
