Use cases of using TAFNEX™ as local reinforcement
Local Tape Placement - Post Reinforcement

Post processing reinforcement by tape placement

reinforced bumper overall-blank
  • UD tape placement enables lower wall thicknesses while maintaining the same mechanical properties
  • 2x layers of UD tape lead to a thickness reduction of the bumper to 40%

Local reinforcements with TAFNEX™ CF-PP UD, can reduce the displacement by 15% and increase the stiffness of the demonstrator without changing the production process.
An additional simulation study shows following results:
  • By only 1x layer UD-Tape (18g) the stiffness increased by 12-24%.
  • With 5x layers of UD-Tape rib structure on the demonstrator were not necessary any more.

Partial reinforcement on basic GF-PP compound

  • Investigation of the effect of one layer of TAFNEX™ combined with PP-GF compound
  • Two variations tested: 
    - One TAFNEX™ layer on top side
    - One TAFNEX™ layer on both sides
  • The mechanical properties can be improved significantly at almost the same density

Local Tape Placement - Tube Winding

TAFNEX™ CF-PP UD as local reinforcement and for vibration reduction in pipe applications

Tube-Vibration
  • Application of TAFNEX™ CF-PP UD on a steel pipe via tube winding
  • Already with 2x layers of UD tape, a vibration reduction was achieved
  • With more than 8 layers of UD tape, the vibrations introduced into the pipe were almost completely eliminated
