ACF is a new bionic energy-absorbing material, which generally refers to the bionic energy-absorbing material of ACF artificial cartilage (also known as ACF bionic energy-absorbing metamaterial). It is a bionic energy-absorbing material invented by Academician Wang, the founder of ACF Laboratory, on the basis of bionics, mechanics, chemistry, metamaterials and other interdisciplinary subjects in 201/kloc-0, after more than 6 years 12000 experiments. This material can absorb more than 90% impact energy, instantly convert kinetic energy into inconspicuous heat energy, and protect human body and valuables from impact injury.

Specifically, it is a typical soft matrix mixed cellular material? At the same time, it is also a bionic metamaterial with three-dimensional ultrastructure based on the function and structure design of human knee cartilage. There are micron-sized holes in the material, and there is a certain relationship between the holes. Gully protrusions are distributed on the surface of the hole, and these heights are all in nanometer height. In a word, ACF material is a kind of soft matrix mixed porous material with micro-nano structure.

As a multi-scale micro-nano structural functional material, ACF material has a wide range of applications, such as sports, medical care, automobiles, aerospace, military industry, architecture, robotics and other fields. ACF materials can play a role as long as they involve impact protection and shock absorption.

Specific application scenarios: human impact protection, such as shoes, helmets, protective gear, protective clothing, body armor; Automobile collision avoidance, such as bumper, collision beam, seat, etc. High-speed rail, aircraft and aircraft buffer energy absorption; Protection of valuables, such as anti-fall of mobile phones and computers, and shock absorption of drones and robots; Others such as military and police training, sports, medical correction, explosion-proof and bullet-proof and so on. ?
