“Biosteel” Fibers for Airbus

January 2019

The European aerospace giant Airbus is teaming up with AMSilk, a maker of advanced polymers based near Munich, to develop a new composite material for the aerospace industry from fibers consisting of synthetically produced spider silk proteins.

The fibers, branded as “Biosteel,” are to be woven or knitted and then used as a lightweight, flexible alternative to carbon components in places on an airplane that are exposed to particularly frequent repeated stresses, thereby reducing repair times for airplanes.

The Biosteel fibers have the same molecular composition as spider silk, which is famous for its strength, flexibility and lightweight structure.
