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
