US study bulletproof vest from fishtail cover

Scientists at the University of California, San Diego, USA (UCSD) are looking for new materials in nature to help create more effective bulletproof jerseys. The research focused on the unique shape and strength of the fish.

The trumpet is an ancient organism that has survived for 35 million years in environments dominated by more aggressive fish. The team used an electron microscope to look at the outer shell and use a microscopic computerized tomography to determine the body characteristics of the fish.

While most fishes have overlapping scales, the outer cover of the fish is made up of innumerable hexagonal scales attached by connectors, similar to those of the infant's skull. born before the hard bone. This structure gives the lid a firm shell, but still has some flexibility.

However, the main reason for the pressure capsule is that the star structure is in the center of each scab, allowing pressure to be distributed evenly over the surface of the body. The researchers also found that the trapped fish's self-defense ability lies in the complex collagen fibers beneath the shell and is difficult to pierce.

The scientists tested the durability of the upper double layer by separating them vertically and horizontally. They found scales that played a major role in the durability of the entire structure. Under impact, they will overlap in zigzag pattern . The research team believes that the defensive characteristics of the fish can help to create a more effective bulletproof vest .

" This destructive structure has evolved for millions of years in nature, and we are studying it with the support of the United States Air Force, hoping it will help us design a bulletproof vest. The Gizmag said on Tuesday, Marc Meyers, a member of the research team.
