Flax fibers are truly green. As a 100% renewable base material, the sustainable fibers are ideally recyclable, biodegradable and compostable. In addition, they are particularly strong and at the same time very light. Flax fibers are also characterized by high dimensional stability, good insulating properties and a low density of 1.4 g/cm³ compared to, for example, glass fibers with 2.54 g/cm³. As a thermal and acoustic insulator, flax fibers offer numerous ecological benefits and also have a low impact on the environment.
In the TWIKE 5, we aimed on the one hand for a high degree of freedom from molding and inherent rigidity of all molding surface parts. On the other hand, an adjusted investment in tools is required in relation to the planned series. And last but not least, in addition to all ecological requirements, a high-quality appearance of all surfaces is essential. Surface and structural components made of flax, partially supported with layers of carbon fibers, meet all these requirements impeccably, and the manufacturing process defined with development partner First Composites GmbH from Niederbreitbach in Rhineland-Palatinate also allows a high-quality and attractive surface in addition to high dimensional accuracy and a high degree of lightweight construction. This is deliberately not lacquered, but only partially foiled for individual coloration and confidently displays the texture of the flax fiber in its sporty, accentuated tailored suit.
The photo shows the recently completed two mold halves for the production of the seat shells, which will also be reinforced with a combination of carbon and flax fibers and will have a seat heater woven into their upper cover layers. A more detailed description of the seats optimized for use in the TWIKE will follow in a later article. Stay tuned.
