Components made of fiber-reinforced plastics have long outgrown their role as elements for use exclusively in high-performance applications in the aerospace sector. Piping for industrial applications and components for both the automotive engineering and the consumer goods industries can now be produced in fully automated tape placement and winding processes, making them relatively economical. In collaboration with Conbility GmbH in Aachen, the Fraunhofer Institute for Production Technology IPT is working to develop the technology to the next level in order to meet industrial requirements in readiness for transfer to industrial application.
Conbility GmbH is looking to add two new systems to its product range using the PrePro technology developed by the Fraunhofer IPT as part of this collaborative venture. The company will provide the technical support for the new standard systems to emerge from cooperation with the Fraunhofer IPT, which are now being marketed by Conbility and will carry out all maintenance on the equipment as well as offering training courses for industrial clients.
The new tape-placement system "PrePro 3D" will be presented by the two partners for the first time at the Composite Materials Fair "JEC World" from 6 to 8 March 2018 in Paris in the AZL Composites in Action Area in Hall 5A, Booth C55.
PrePro 3D: Modular tape applicators with VCSEL-technology
The PrePro-3D-applicator is available as a modular system and can be integrated as a plug-in retrofit in existing robot or machine systems. It is suitable for processing pre-impregnated semi-finished products known as prepregs. The outstanding feature of this setup is that this allows complex, three-dimensional preforms to be produced directly.
The advanced laser technology used can accommodate a wide range of process temperature, enabling the system to perform laser-assisted thermoplastic tape placement and to process thermoset prepregs with ease. The system is capable of producing tubular components as well as complex 3D structures. In order to facilitate integration in existing equipment, the product has a de-centralized control system which communicate with the machine system via standard interface, thereby ensuring a particularly high level of versatility in terms of applications.
Fraunhofer IPT and Conbility: From research to industrial application
Fraunhofer IPT in Aachen can draw on over 30 years of experience in the development of tape-placement and winding systems. Different versions of placement and winding systems as well as customized special-purpose machines have been developed, set up, optimized and transferred to industrial application in recent years as part of numerous publicly funded projects and in collaborative ventures with industry.
Not only has the Fraunhofer IPT acquired a thorough and deep understanding of process control and inline quality assurance systems which it develops and refines continually; it also has extensive experience in the use of a diverse range of heat sources such as hot gas, infrared projectors microwave and laser technology.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
