The Future of Composite Manufacturing

NETZSCH presents new sensor for real-time process analytics and paves the way to mid- and high-volume production in the composites industry

The new sensor meets the requirements of the industry regarding

  • A temperature range up to 220°C
  • A pressure resistivity up to 300 bars
  • An easy integration into and communication with the superordinate procces control

While having a look inside the mold the sensor provides the following information:

  • Resin flow-front detection
  • Flow behavior
  • Gel-point
  • Cure behavior
  • Glass-transition evolution

What can our sensor do what others can't?

Our new sensor can characterize the material behavior of carbon composites without the need of any further preparations

It is suitable for a wide range of tasks like:

  • Reactive FRP processes
  • High in-mold pressures (RTM, PCM, SMC)
  • Characterization of materials which contain conductive fillers like Carbon Composites

The performance of the sensor was proven during the run-time of the BMBF funded and AVK awarded project “OPTO-Light” involving the partners ARGES, AZL of RWTH Aachen University, BMW, Carl Zeiss Optotechnik, KraussMaffei Technologies, Precitec and Sensortherm. It was proven that this new sensor creates a benefit for the intelligent self-adapting process management based on the curing behavior aiming the compensation of deviations in semi-finished products and the reduction of cycle times and scrap. Through communication with the process control system, the new sensor technology controlled the process in such a way that an optimal adhesion of dissimilar materials in a cascaded process could be achieved.
