The Thin ply.

Thin plies give you the freedom to optimize the reinforcement design. At the same time this technology saves weight and reduces laminate thickness.

Thin plies (<0,05 mm/layer) suppress or delay crack initiation in loaded composite structures. Thereby allowing for manufacturing of lighter, stiffer and more durable composite products.

Thin plies optimize your carbon fiber usage.

TeXtreme® Technology is flexible and tow-size independent which allows the development of optimized reinforcement solutions, tailor-made for specific needs of the application. Without sacrificing rigidness or strength it also can improve impact tolerance as well as your surface smoothness. TeXtreme® is available in a wide variety of configurations.

Impact tolerance

The ply thickness of each separate layer is clearly connected to the strength of the composite part. The benefit achieved by thin TeXtreme® Spread Tow reinforcements compared to the apparent strength is illustrated above.

Combining the weight savings possible from the optimal fiber structure with the thin nature of Spread Tow reinforcements renders a performance that no other composite reinforcement can match.
