Technologies for automated forming of dry fibers and prepregs

The advanced forming of 2D dry fabrics or prepreg stacks is a key element to a costeffectivecomposite production (CFRP / GFRP), especially for today’s and futurehigh-volume production in Aerospace and Automotive industry. Therefore, theautomated forming process is one of the major drivers for a later high-quality RTM(Resin Transfer Molding) or Prepreg curing process.

ALPEX Technologies is a turn-key solution partner for customer-specific 3D formingsystems for dry preforms or prepreg stacks. ALPEX engineers, designs andmanufactures all required tooling systems from 2D cutting of the fibers to final 3Dtrimming of dry and pre-impregnated fabrics.
