Textile high-tech stability for the field of space


At 19:41 on April 20, "day boat one" cargo spacecraft in China's Hainan Wenchang space launch site by the "Long March 7" Yao two carrier launched successfully launched. As China's independent development of the first cargo spacecraft, "the day boat on the 1st" called China's most cattle "Express brother", April 22 at 12:23 in space with the "Temple II" successfully completed automatic rendezvous Docking, the implementation of propellant in orbit addition, break and master the propellant in orbit and other key technologies.
"Semi-rigid battery substrate glass fiber grid" (referred to as "semi-rigid glass fiber grid") developed by Dong Nanliang, director of Engineering Research Center of Industrial Textiles Ministry of Education, Donghua University, was laid for "Tianzhou No.1" Energy-powered "glass wings".
It is understood that this is following the help of "Temple One", "Temple II" after flying, half of the glass fiber grid once again successfully used in the "day boat one" cargo spacecraft launch. To this end, the China Aerospace Science and Technology Corporation eighth Institute in the cargo spacecraft after the successful launch of the first time to the Donghua University research team sent a letter of thanks, thanks to the East China scientific research workers for the "day boat one" launch Related contributions.
Chen Nan Liang team developed semi-rigid glass mesh, is a glass fiber as raw material, the use of warp knitting process to produce high-density high-quality warp knitted fabric. In order to overcome the general requirements of glass fiber in strength, elongation, softness and other performance difficult to meet the requirements of aerospace products and materials, Chen Nanliang team and Nanjing Glass Fiber Research Institute, developed a high strength, low elongation, high soft special Glass fiber, from the source to ensure the high quality of aerospace fabrics. With special glass fiber, production technology and weaving equipment should also be replaced, so, Chen Nanliang independent research and development of the warp knot technology theory, the successful development of special glass fiber for the special warping process, and their own hands-on design To create China's first space special glass fiber weaving machine.
From raw materials to technology until the equipment, Chen Nanliang team's independent innovation has never stopped the pace. In order to further optimize the carrier structure of the battery windsurfing, Chen Nanliang team in turn made the glass fiber fabric grid shape. According to Chen Nanliang introduction, this is done on the one hand can effectively help the battery to reduce the weight of the windsurfing, so that the overall vehicle more light weight, on the other hand the battery can be through the grid for positive and negative double-sided power generation, power generation can be increased by 15 %.
Chen Nanliang said that although the semi-just fiberglass mesh material research originated in boosting the "Temple One" flying, but he and his team members still have a more ambitious goal, that is to promote China's warp knitting technology into the high-end Technology application of the industrialization process. The launch of the "day boat one" mainly follows the "Temple II" used by the "semi-rigid battery substrate glass fiber grid" technical results. "In the early large number of experiments and practice on the basis of the current spacecraft battery substrate in the field of research technology has been relatively mature, the relevant results in China's aerospace applications have also entered a stable supply period, the future we will continue Adhere to scientific and technological innovation, the development of space for the motherland, the construction of aerospace power to make new contributions. "Chen Nanliang said.
