Compression molding

  • Compression molding is already used with TPFL® pellets
  • Development and characterization of “TPFL® flakes” is ongoing
  • Goal is to make HP composites with injection

Bladder inflation molding

Use of TPFL® braids :

  • Easy lay-up
  • No joints, no overlap
  • Possibility of evolutive sections, curved parts

Real applications : Sporting goods with Carbon/PA12 TPFL® braids. Typical cure cycle: >5‘, 10 bars, T° = Tf +30°C


Diaphragm forming

Key feature of TPFL® materials :

  • Fibers are slipping during the process
  • Yarns are elongating (Up to 20%)
  • Absence of wrinkles in the edges

Cold stamping

Techniques that is widely used for consolidated thermoplastics, allowing fast processing

When using TPFL® materials that are not consolidated, consolidation requires:

  • Pre-heating of the material to processing temperature, typically Tf + 30°C
  • Time to allow the polymer to flow and wet-out the fiber
  • Cooling down the material until the T°< Tg
