Barrday TF300 PEKK Semi-Preg

Barrday TF300 PEKK Semi-Preg is a polyetherketoneketone (PEKK) fabric semi-preg that processes in the 670-700oF (355-370oC) temperature range. The materials are used in a variety of high performance, structural composite applications. PEKK is a high temperature semi-crystalline polymer with a good combination of toughness, chemical and solvent resistance, low moisture absorption and superior FST properties.

Process Information

The following are general recommendations for successful processing. Other consolidation cycles are possible. Temperatures listed are for in-part thermocouple readings. Adjustments may be required to achieve optimum results in your specific manufacturing environment.

Press Cycle :

  • Heat part to 725-750oF (385-400oC)
  • Increase pressure to 250 psi (17 bar)
  • Hold for 30 min
  • Cool to room temp. at 10oF (5oC)/min.
  • Do not remove pressure until temp. < 275oF (135oC)

Autoclave Cycle:

  • Apply vacuum pressure
  • Heat part to 725-750oF (385-400oC)
  • Increase pressure to 150 - 250 psi (10 - 17 bar)
  • Hold for 30 min.
  • Cool to room temp. at 10oF (5oC)/min.
  • Do not remove pressure until temp. < 275oF (135oC)
