Bulletproof material new varieties of fish scales?

Arapaima giant Amazon is attracting the attention of scientists at the University of California, San Diego to create super-durable materials.

>>> Graphene: The material can change the world

Through the observation that the tiger fish (Piranha) have very strong and sharp teeth attack Arapaima arowana in the Amazon, but was unable to penetrate the two scales to jail arowanas.

Arowana scales are like a laminate with a dynamic force

Researchers said the Arowana scales were very distinctive. Outside of the Arowana scales is a layer of mineral material, while inside it has elastic collagen fibers, forming a flexible laminate, almost like a piece of cloth.

The research will open the secret to the production of high-strength materials such as bulletproof materials, puncture-proof gloves, safety glasses and durable CDs.

In Canada, scientists are working on new materials, inspired by bass scabbits, which can create shape-changing wings, CDs, biomedical devices and safety goggles. whole. They hope to combine with the study of dragonfish scales to create a more durable composite material.
