Among automotive innovations showcased at this year’s JEC World in Paris was a load floor made with Faurecia’s Flaxpreg composite technology that is being employed this year in selected new Peugeot vehicles.
Flaxpreg is made from very long flax fibres and acrylic resins, making it a 50% natural materials part.
Its benefits include high mechanical performance and significant 35% less weight than market-competing products, which equates to shedding 1kg of weight from a vehicle. It also allows designers considerable freedom in shaping their designs.
The flax component is based on Flaxtape made by Lineo, headquartered in Meulebeke, Belgium. Flaxtape consists of unidirectional (UD) flax fibres, which in a patented process are stretched and then sprayed with water and dried, so that the natural cement in the flax fibres is all that’s required to bind the material together.
The process was developed in a research project involving Lineo, Peugeot and its Tier 1 supplier Faurecia, which is headquartered in Nanterre, France.
Lineo’s Flaxtape was the starting point for Flaxpreg sandwich panel composites for automotive interior parts, including load floors, door panels, roof trim, instrument panels and seat backs.
Flaxpreg consists of plies of the Flaxtape around a honeycomb core combined with BASF’s Acrodur water-based binding system.
Peugeot and Faurecia are commencing the production of various parts based on Flaxpreg in 2017 and Lineo has expanded its Flaxtape production to meet estimated demand of a million metres per year.
