AMSilk partners with Airbus to develop the next generation of composite fibers for lightweight, high-performance planes; BioSteel

AMSilk, the first industrial supplier of synthetic silk biopolymers, has entered a joint cooperation agreement with Airbus to develop the new era of composites for use in the aerospace industry.

In recent years, the aerospace industry has shifted from metal and steel fuselage and wings to carbon fiber composite materials, primarily in an effort to decrease the plane’s weight and save fuel over time. Airbus, committed to remaining at the forefront of aerospace innovation, is the first in the industry to experiment with this new material. It intends to explore how AMSilk’s Biosteel fiber can allow it to approach the design and construction of their planes in an entirely new way.

Biosteel fiber is made from a biopolymer based on natural spider silk, a material known for its strength, flexibility and toughness. AMSilk produces Biosteel fiber through a closed-loop biotechnological process that renders the product highly sustainable, with no petroleum inputs.

The new composite material will be built using AMSilk’s Biosteel fiber technology, which enables lightweight construction with multiple shock resistance and flexibility.



From the link they say.
" AMSilk high-performance biopolymers give such
products unique properties. Among other things, the polymers are
biocompatible, safe and robust.."

There are many concerns for carbon fibre risks and the industry understanding treats it as no different to asbestos.
The worry there should be with increasing volume and volumes entering waste steams including unregulated, the carbon fibre risks become problematic.

I wonder if this new material is in similar category.


Is artificial spider silk really stronger, safer and/or more ecological than carbon fiber?

If so and if it can be mass produced at a lower cost, lighter planes (and future e-planes and e-vehicles) and improved wind mill blades could be a possibility?
