Regio 2N train cabin made with natural fibers
The largest composite part reinforced with natural fibers
This demonstrator was presented for the first time at the JEC World show in Paris Nord Villepinte in March 2017. The part is the result of collaboration among participants in the investment project for the SINFONI “forward-looking” program.

The cabin of the Regio 2N train is usually produced with glass fibers by infusion and hand lay-up molding. It has been completely redesigned by computer to replace this synthetic material with fibers of flax and hemp as reinforcements. The production of the Regio 2N cabin was carried out in cooperation between producers, industrials and experts, in order to select the right stratifications and to optimize the manufacturing techniques.
The use of plant fibers as a reinforcement in the railway industry has been possible with the same processing methods while at the same time allowing a weight gain on the part of at least 20%.
