The Fraunhofer Institute for Microstructure of Materials and Systems (IMWS) and the material supplier DOMO Engineering Plastics jointly launched a high-performance thermoplastic (HighPerTherm) research and development project, and developed a new type of glass fiber reinforced polymer. Amide (PA) tapes for innovative low-cost lightweight constructions suitable for mass production. The aim is to expand the application range of semi-finished products made of continuous fiber-reinforced thermoplastic tapes for effective use in structures subjected to high stress.
As part of this project, the Fraunhofer Institute for Microstructure of Materials and Systems (IMWS) is working on optimizing and further developing process technologies and manufacturing methods for the production of continuous fiber-reinforced thermoplastic semi-finished products. The matrix system developed by DOMO Engineering Plastics as well as extensive analysis and optimization of process parameters have resulted in significantly improved mechanical properties of the tape semi-finished product compared to conventional materials. In addition, the newly developed matrix system significantly improves processability, significantly improves fiber wetting in semi-finished products and improves long-term process stability.

“Through targeted material and process development steps, we increased the fiber volume fraction in the tape semi-finished product and identified the optimum parameters to be able to produce a UD tape semi-finished product with optimized mechanical properties,” Tillner said.
DOMO Engineering Plastics is a PA6 and PA66 manufacturer based in Belgium. Since 2022, DOMO Engineering Plastics has been selling UD tapes under the trade name Technyl-Lite.
Fiber-reinforced plastics can play an important role in reducing CO2 emissions by replacing metal materials and structures. Through lightweight construction, raw materials, costs and energy can be saved during the production, use and recycling of products.
New fiberglass-reinforced polyamide (PA) tapes consist of continuous reinforcing fibers and a plastic matrix, which offer better mechanical properties than conventional particle or fiber composite plastics. Due to their versatility, they are used in mechanical engineering as well as in various fields including automotive, aerospace, building and construction.
