Mission & sustainability statement

Following nature's example, fibionic uses reinforcement material exactly where it is needed. fibionic is a service and production company for the optimized design and production of continuous fiber-reinforced composites (carbon, glass or natural fibers) in mechanically stressed structures.



The idea was born

“We have been looking for a solution for a long time on how to optimize the material to make components lighter and reduce costs,” says Thomas Rettenwander today. At the same time, one important aspect was always to protect the environment by avoiding material waste.

2019 - 2021

Trials, trials, trials - patent granted

In countless tests, a technology was developed that stands out above all in series production with its speed, stability and resource savings.

This process was then successfully patented.


Company formation fibionic

Together with his friend and colleague Johannes Mandler, Thomas Rettenwander founded the start-up fibionic with the support of Austria Wirtschaftsservice AWS - in the Tyrolean town of Thaur, near Innsbruck, in the attic and workshop of his house.
