Tailored Blank Line
Faster Tape-Laying Procedure
With the tailored blank line using the Fiberforge and Fibercon systems, Dieffenbacher GmbH, Eppingen, Germany, has developed a solution for the large-series production of locally reinforced thermoplastic components.
In the first step, the Fiberforge produces near-net-shape composite lay-ups from carbon fiber or glass fiber pre-preg tapes. One laying cycle lasts about one second, making this system the fastest tape laying system in the world. After a laying pattern is defined, the tapes can be rolled off of coils and laid according to that pattern. The Fiberforge system can carry four of these coils. This makes it possible to mix different materials in one tape lay-up. Even the width and thickness of the tapes can be varied.
With a new angle-cutting system, the start and end of the tape can be cut either straight or at an angle of plus or minus 45 degrees. Precise and near-net-shape tape laying reduces excess bleed cuttings. An automatic coil exchange system guarantees uninterrupted production.
The complementary Fibercon process line uses vacuum bag forming to form the tape lay-ups into a near-net-shape laminate. The Fibercon can process several lay-ups simultaneously and has impressively short cycle times. The vacuum bag forming system minimizes air pockets and material faults, producing unparalleled laminate quality.
Together with downstream systems such as handling robots and compression molds, the Fiberforge and Fibercon systems make it possible to produce more than one million components per year.
