Solid progress with Samba for Cevotec

It’s been a busy 2017 for Cevotec, following the market launch of its Samba industrial fibre patch placement preforming system and accompanying Artist Studio at JEC World in Paris.

“After several previews in a VR environment, the Samba could be viewed for the first time creating a complex fibre preform at JEC World,” says Felix Michl, Cevotec CTO. “The speed of one patch per second and the accuracy of the lay-up system impressed many visitors to the show.”

“We scored a major success with the market launch and only three months later, we were able to demonstrate the world’s first patched aircraft window funnel at the Paris Air Show,” adds MD Thorsten Groene.

The biaxially curved funnel preform requires a constant radial and circumferentially-oriented fibre architecture and presents a real challenge in manufacturing.

By the time of Composite Europe in Stuttgart in September, Cevotec was able to showcase some requested extensions to the system.

In addition to Artist Studio, a plugin for a commercial FE-based modeling software is being developed that enables an automated patch-laminate modeling for simulating the mechanical behaviour. On the hardware side, scalable Samba Series system variants were presented to meet the requirements of almost every production setting.

In addition to Samba Pro, which is particularly suitable for a flexible, high-volume batch production of components, Samba Scale for high-volume production processes up to 15 kg of material per hour has been introduced. Attached to a production line, the Samba Scale cells reach a constant throughput of up to 100 kg per hour, even when producing highly complex 3D-preforms. As a result of its multiple patch robots, hybrid fibre components made from, for example, carbon and glass fibres, can be integrally built, increasing the developer’s design freedom in respect of materials.

Samba Step, meanwhile, is made for small scale production prototyping and R&D, with a flexible degree of automation and a realistic price.

Alongside these developments, Cevotec’s specialists are also focusing on the materials which the Samba systems can process and the company’s high-quality dry carbon fibre tape – which is also suitable for other fibre placement processes such as AFP and ATL – will soon be commercially available.

In addition, Cevotec will launch a version of Samba for prepreg processing early in 2018.
