6. Carbon fiber production step by step

7. CFRP production SGL ACF. plant Wackersdorf.
Biaxial equipment, decoiling, spread threads, knit layers, temper scrims/apply binder, wind up scrims. The carbon fiber threads are decoiled depending on the working width and grammage from 90-560 coils simultaneously, the deflection over a plurality of round profiles results in an increase of the yarn width, carbon fiber and glass fiber layer will sewn with a sewing thread according to a defined sewing pattern together to a scrim, by heat/temperature, the sewing thread is shrunk. Then applied the binder powder, which is also heated so that the powder is softened, is adhered to the scrim and partially penetrates into the structure. Scrim is rolled up on core and cut off after reaching the piece length.

8. BMW i3 production, plant Leipzig. CFRP production, preform installation. Stacks (textile mats) are moved to preform installation, process from front, laterally close. Stacks arrive in installation, go up to preforming. A mat is taken and inserted. Geometry of the component is created. Preform parts cut by robots. Preform tool front laterally, total and nearby. Ready preform parts on the assembly line. Supervisory personnel passes by the oxidation furnaces.

9. RTM Presse.
