During this Spring Festival, Gong Xiaozhou, a 35-year-old female doctor from the School of Textiles of Wuhan Textile University, still spent her time in the laboratory. This Shanghai girl who returned from studying abroad did not go home on New Year’s Eve for three consecutive years, focusing on her “three-dimensional textile machine.” In order to develop this “three-dimensional textile machine”, the team she led has been working hard for nine years since 2006. At the end of November last year, the “three-dimensional textile machine” woven the first three-dimensional three-dimensional textile fabric that could be used as an “iron shirt”. Gong Xiaozhou was so excited that he couldn’t sleep all night.
Gong Xiaozhou told the Wuhan Evening News reporter that this project has signed an intention to transform the results with the company and will be put into production soon. She has to perfect every detail to ensure that there are no mistakes.
It’s okay to stab or scratch with a knife
“Iron Shirt” is a famous body-protecting hard Qigong in Chinese Kung Fu. It is said that those who have mastered this skill can not only withstand punches and kicks without being hurt, but even swords and guns cannot hurt them. The cloth woven by the “three-dimensional textile machine” developed by Gong Xiaozhou’s team has this “magic effect.” “Comparing it with steel, the three-dimensional textiles woven are 3/4 lighter than steel, but 6-7 times stronger than steel. The cloth woven from light carbon fiber is even lighter than cotton!” Gong Xiaozhou said.
Gong Xiaozhou took out a long strip of cloth in the shape of a belt: “Try it.”
The reporter used a lot of force to stab the cloth strip several times with a knife, and then slashed it several times. The cloth strip only left a few fine marks that were difficult to see with the naked eye. Gong Xiaozhou told reporters that this is only a semi-finished product, and the final product will be difficult for bullets to penetrate, let alone guns and knives.
Why is this cloth so hard?
Lin Fusheng, another leader of the team and a professor at the School of Mechanical Engineering of the school, explained that the raw materials used for this piece of fabric are glass fiber, quartz fiber, and carbon fiber, and are woven by taking the strengths of all fiber materials. 6-7 times harder than steel is calculated based on the density and properties of these materials. “Teacher Gong studied for her master’s degree and doctorate at the University of Manchester in the UK. Her tutor is a world-leading master in three-dimensional textile weaving technology. This master once conducted an experiment with the same three-dimensional textile cloth and shot it with a pistol from 10 meters away. , the cloth was not shot through or deformed, and these processes were later used in British body armor and various police equipment. ”
