The only idea is to steam beer, you are the future of sustainable industrial design

Researchers know that the shells of crustaceans such as shrimp, crabs, lobsters . do not have any special chemical ingredients to become so hard. Instead, they have a unique micro structure.

So far, we have not been able to create perfect artificial materials. Take concrete, for example, very powerful, amazingly load-bearing, allowing people to build bridges across the sea and skyscrapers. However, it is also quite brittle, easily cracked if the temperature changes suddenly.

Now, researchers from California Riverside University have discovered a promising way to create more sustainable materials and designs (vehicles, helmets, batteries .) in the future. This inspiration comes from billions of years of evolution and micro architecture in crustaceans' shells .

"Whenever we go to the material lab, we make bad things ." said Pablo Zavattieri, a researcher at Lyles School of Civil Engineering. "Instead, we are working on using design principles in nature, how to increase the properties of materials without sacrificing other values."

Over the past decade, Zavattieri has collaborated with California Riverside University to learn how living organisms create the most impressive structures on earth. Initially, the team studied shells, with the main ingredient being calcium carbonate (like human bones). They have impressive properties, but they find something much better.

The more surface (also called headline shrimp).

"While studying the shells, we accidentally discovered that the surface could break the shell with a powerful punch with the extra foot like a hammer , " Zavattieri said. "We will study the [hammer] of the surface".

Researchers know that the shells of crustaceans such as shrimp, crabs, lobsters . do not have any special chemical ingredients to become so hard. Instead, they have a unique microstructure - the fiber structure piles up in a single direction - each layer changes its orientation a bit stacked up like a helicoidal staircase.

Mechanical engineers have used the inner fiber structure to enhance the strength of man-made materials, whether it is "fibrous" in carbon fiber or reinforced in concrete, they have developed a similar method. like crustaceans.

But the difference is that they have spinning layers. Artificial synthetic materials usually have only their fibers running in a single direction across the entire material.

Materials based on crustacean structure have different cracks in different locations.

On the other hand, materials based on crustacean structure have different cracks in different locations. While concrete, carbon fiber . create large cracks. However, by adding spiral structure, cracks in artificial materials will basically be difficult to spread.

"Instead of creating a large crack, it will create many nanoscale cracks," Zavattieri said. These cracks create what scientists call "graceful failure", or micro-damage that can absorb external influences without damaging the structure of the entire system. Indeed, if we can make concrete like Zavattieri said, future buildings will have much better resistance to earthquakes.

3D printers will shape concrete into a small spiral structure, making the concrete more resistant to stress.

Why say concrete is a promising material with this structure? Simply because we don't need to add anything to the mix. Instead, 3D printers shape concrete into a small spiral structure, making the concrete more resistant to stress.

Not only concrete, helmets, car tires and batteries are inherited from the natural design in crustacean structure.

The main battery is a great example of the wear and tear of materials that few people know about: They decompose when charging or discharging due to chemical reactions. With spiral structure, the mechanical structure inside the battery will be more durable, meaning longer energy generation.
