Quality control

CFRP Test stave two prepreg with integrated wood and Rohacel foam Studies on the determination of the quality control (delamination) for the production of CFRP (carbon-fiber-reinforced polymer) staves using X-rays were performed successfully. Further studies are planned with a Test stave (for example with Pulse Thermography)

  • Vacuum-operated mode using hydrostatic pressure
  • Active cooling pipe Dext 2,0 mm d int 1,8 mm

  • Upstream routing Dext 4 mm d int 2 mm
  • Pressure drop must be evaluated
  • Cooling capacity has yet to be determined
  • (last information about Barrel chips from University

Giessen 1W/cm²)
