Spider Web Glass

Certain spiders protect their delicately crafted insect nets with a special silk rope that reflects ultraviolet rays. Birds can see the ultraviolet rays and recognize the webs as obstacles they should avoid.

If engineers can reproduce the effect, it might save birds from their occasional accidental suicide runs into glassy buildings. German engineers at Arnold Glas copied the spiders and glazed their Ornilux-brand glass with a web-like pattern of ultraviolet-reflecting coating to save the birds from high-speed headaches.

Technical application:

innovative glas against birds collision

Seashells are harder than ceramics and can be printed by your desktop 3D printer?

sea_shellFor example, an abalone shell is stronger than high-tech ceramics because of its internal structure. Diatom shells are made of silica (glass), but they are extremely strong because of their stress-distributing pattern of holes.cutter

Like nature, 3-D printers can excel at building complex structures from simple materials, said Benyus. Both use an additive process, meaning larger pieces are built up from smaller ones.

Building based on mechanical stiffness of sea-sponges

sponge The Euplectella aspergillum is a cylindrical sponge that lives intropical waters. It has a height of 45 cm. Its exoskeleton conbionic_buildingsists of hydrated, amorphous silicon dioxide organized into a complexnetwork of spicules that supports the structure. These fibres, whichare 5-10 cm long and as thin as a hair form a crown at the foot ofthe network that anchors the sponge to the bottom of the ocean.

Technical application:

tall structures

Self healing materials

genMany processes in organisms based on the self-organization of biological components. For materials scientists, such substances are a dream: you react autonomously to their environment and can adapt to this different conditions. At the U.S. MIT researchers aim to produce such wonders molecules artificially.

Hook fastener with up to 35 tonns / m²

klettblumeHook and loop fasteners have become commonplace features of both industry and households.

hookfastener

 

These fasteners are resistant to chemicals and can withstand a tensile load of up to 35 tonnes per square meter at temperatures as high as 800°C.

Technical application:

Metaklett is basically suitable for use in all areas that require easily opened but stable fasteners, for example air-conditioning and ventilation systems in building services engineering and automotive construction.

Fluid wood instead of plastic for incredible structures

fluid_woodArboform acts a lot like any other petroleum-based plastic to a manufacturer. It can be injection-molded as a heated liquid to form any shape. But Arboform is not made of petroleum. Instead, it is made of “Lignin, combined with resins, flax and other natural fibers” as described in this article:

Technical application:

substitute plastic
