Cevotec enables manufacturers to build complex fiber composites in high volume and quality – by smart process automation based on Fiber Patch Placement technology. With SAMBA Series, Cevotec offers tailored, automated fiber lay-up systems for challenging 3D geometries and laminates with complex fiber orientation. ARTIST STUDIO is the matching CAE software for generating patch-based fiber laminates and automated robot programming. Along with development services that include FE-based modeling and simulation, Cevotec offers the entire process chain from digital design to final fiber product.

  • Cevotec successful at JEC World 2019 and joins Fiber Placement Center

    “JEC World 2019 show was definitely a success for Cevotec”, states Thorsten Groene, Managing Director of Cevotec.

    The main eyecatcher certainly was a demonstrator section of a major component of an engine nacelle structure, made in cooperation with and for SAFRAN Nacelles, demonstrating how Fiber Patch Placement handles multi-material lay-up of an aerospace sandwich component. “These components”, explains Felix Michl, CTO of Cevotec, “in aerospace industry find their main applications in winglets, stabilizers (horizontal and vertical), flight control surfaces, radar domes, aerodynamic fairings and nacelle structures.” All of them have to be lightweight yet resilient to meet the industry’s continuous strive for emissions reduction and greener aircrafts, supported by more efficient structures. In the production of such components, the geometric complexity and the multi-material mix pose a particular challenge.

  • Industry 4.0 automation for building complex composites

    Cevotec’s SAMBA Multi production systems feature parallel feeding units for processing up to 4 different materials and placing them precisely on 3D sandwich cores. The placement unit mounted on a linear axis enables the production of particularly large components. By scaling the patches to DIN-A-4-dimensions, a high material throughput is ensured. An integrated, automated gripper station enables the switching to smaller gripper and patch sizes for lay-up in high-complexity areas of the part during the process.
    The technology allows for a highly controllable component production cycle, as the production cycle itself is composed of a series of individual patch placement cycles, which can be tightly controlled by means of self-corrective algorithms: So, the first unit of the in-process material control identifies the quality of each patch that is cut. The second the relative position of the patch on the placement gripper once picked up. Thereby, the in-process quality control ensures that only 100% in-spec raw material is being placed exactly at the calculated position.
    Additional industry 4.0 modules cover predictive maintenance and in-depth analytics on production data, enabling key insights into process reliability and repeatability. Correlating the data with actual layup quality enables adjusting process parameters in real-time and – prospectively – also AI-assisted. Ultimately, part quality can be ensured only by controlling process parameters.
    Thus, manufacturers now have more options to improve their part quality and also equipment reliability & availability. These benefits usually come as an upside to baseline savings of 20% – 60% in production cost & time resulting when switching from manual lay-up to Fiber Patch Placement.
