Extract From Report: ...."Tommy Fristedt, president of LayStitch Technologies (Highland, Mich., USA), reviewed the advantages offered by tailored fiber placement (TFP) technology of the type offered by his firm. TFP technology stitches carbon fiber onto a carrier fabric in prescribed shapes that can then be used as preforms in composites molding processes. The system uses a stationary stitching head over a horizontally oriented backing material that is moved relative to the head. Fristedt says the machine applies 1,000 stitches/min, offers full orientation freedom, allows the user to mix material types, can stitch dry fiber or towpreg and is compatible with RTM, compression molding or injection molding. Notable applications include a mountain bike frame booster, a robot arm, Airbus A350 XWB window frame, boat propeller and helicopter longerons."....

Extract From Article: ...."Interest also was high in a paper presented by Tommy Fristedt of LayStitch Technologies (Highland, Mich.) on a tailored fiber placement technique that produces a flat preform in a process he likened to printing, using stitched carbon tows for local reinforcement. The company claims almost zero waste, because the preform can be stitched and layed down exactly as needed, and stitching can be selective for maximum conformability. The company’s products have been used by Airbus for aircraft window frames, and Fristedt believes the low cost and improved speed, as well as the ability to incorporate electronic wires, for example, can yield cost-effective preforms for automotive applications"....
