On August 24th, the South China Sea Hong Kong Macao Youth Employment and Entrepreneurship Exchange Event, hosted by the Human Resources and Social Security Bureau of Nanhai District, Foshan City and the United Front Work Department of Nanhai District Committee, visited ACF Soft Valley with the aim of learning the technical culture of excellent enterprises and enhancing the enthusiasm for innovation and entrepreneurship in the mainland of Nanhai Hong Kong Macao.

To promote communication and interaction with young people from South China Sea, Hong Kong, and Macau, ACF Soft Valley staff led them to visit the exhibition hall, mainly showcasing the hazards of impact collisions, the principles of artificial cartilage energy absorption technology, material morphology, material characteristics, and scene applications. There were also some interesting small experiments interspersed in the middle.

The exhibition hall commentator explained that current sports, transportation, and industry are filled with impacts and vibrations, which affect human life safety and industrial production efficiency. Traditional protective materials also provide limited protection and cannot withstand huge impacts and vibrations. ACF artificial cartilage energy absorbing material, as a biomimetic energy absorbing material, was invented by Wang Bowei's team after 6 years and 12000 failed experiments. It has the advantages of extreme buffering, strong protection, strong support, high stability, comfort and thinness, and plays a crucial role in human sports, industrial manufacturing, transportation vehicles, and even in major fields such as aerospace and military industry.

In order to give everyone a closer understanding of ACF biomimetic cartilage metamaterials, the instructor invited a young guest to demonstrate a comparative test of shot put. A 15 pound shot put (equivalent to 10 tons of impact force) was thrown at ordinary EVA material and ACF material covered with glass sheets, respectively. The glass sheets covered with EVA material were smashed to pieces, while the glass sheets covered with ACF material were intact, confirming that the buffering and energy absorption performance of ACF material is much higher than that of traditional materials.

Subsequently, the narrator introduced its various forms, such as sheets, rolls, black films, transparent films, etc. While everyone was amazed by the diversity of materials, the narrator also opened the door to the understanding of metamaterials among the young people present. Firstly, ACF energy absorbing materials and ASF high elastic materials belong to the same material, but their structures are different. Therefore, the characteristic of ACF material performance is energy absorption, while ASF material performance is high elasticity. Secondly, ACF sheets can become very soft or very hard at different speeds, reflecting that the characteristics exhibited by the same material and structure are contradictory; Thirdly, under high-speed impact, BCM metamaterials generate negative modulus and negative density.

Under the interesting and vivid speech of the instructor, the atmosphere on site became lively.

When introducing the application of ACF biomimetic cartilage metamaterials in the field of human protection, young people from South China Sea, Hong Kong and Macao have approached to learn about TSG skiing protective equipment, elderly anti fall pants, gymnastics training pants, and artificial cartilage biomimetic energy absorbing insoles. Many young guests expressed that these civilian protective footwear and clothing are very meaningful, which can greatly reduce the risk of falls and impacts during daily walking and sports, and reduce the impact force injury. At present, the shoes and clothing developed and produced by ACF are highly favored by consumers, ensuring their safety.

As a national intellectual property advantage enterprise and a specialized and innovative enterprise in Guangdong Province, ACF Soft Valley has 4 basic laboratories, 6 university joint laboratories, and 2 achievement transformation platforms. This time, it will conduct technical and cultural exchanges with young people from South China Sea, Hong Kong, and Macao.
