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
