Aerospace
With the development of human spacecraft towards larger, stronger and farther directions, there is an urgent demand for new high-performance materials. Warp knitted grid structures are widely used in the aerospace field, and are key materials for developing semi-rigid solar panels and large space borne deployable antennas. In order to make the space station larger and stay in space longer, glass fiber warp knitted grid materials are needed as the key supporting materials of solar cells. Warp knitted metal mesh reflector materials are used as key materials for large deployable antennas to help satellites fly farther. Such mesh materials have been used in "Tiangong-1", "Tiangong-2" and "Tianzhou-1" spacecraft. Metal mesh products have been successfully applied in many high-performance satellites such as "Beidou" navigation, "Tiantong-1" and "Chang'e-4" Queqiao ", greatly improving China's space station technology and satellite communication capabilities.
Materials of wind turbine blades
With the in-depth development of the wind power industry, the requirements for blades are becoming longer and longer. The market demand for application materials to be prepared with lightweight, low cost and high efficiency is proposed. Composite materials are the best choice to meet this demand. Multi axial warp knitted reinforced fabrics have the advantages of high strength modulus, quasi isotropy, good shear resistance, good delamination resistance, high efficiency and low cost, and have been widely used in wind power blades. At present, high-speed multi axial warp knitting processing technology of glass fiber, carbon fiber/glass fiber and carbon fiber has been realized in China, and the technology and industrialization of carbon fiber multi axial warp knitting equipment have been broken through, meeting the requirements of large strand carbon fiber expansion, multi axial ply full specification knitting technology, and realizing full specification, low-cost knitting and composite material application of carbon fiber multi axial fabric.
Flexible inflatable and deployable materials
Large spacing three-dimensional fabric reinforced flexible composite material is a new type of inflatable structural material. Different from traditional inflatable materials, its inherent interval wire drawing can achieve various shape plasticity after inflation, and endow the material with excellent structural stiffness and modulus. It expands the application scene of inflatable materials and plays a huge role in military, aerospace, construction, agriculture and forestry, biomedicine, etc. It can be used in high-end sports equipment Inflatable car seat cushion, shelter hospital isolation cabin, fire rescue cushion, light high suspension bridge, aircraft life-saving slideway, aircraft parking garage, military hovercraft, aircraft, inflatable structure space capsule and other products.
Biomedical
Biomedical textiles are a new field formed by the combination of textile technology and medical science. With the development of life medicine technology, there is a large demand for new textile structural materials. The knitted structure artificial blood vessels are mostly prepared by the method of warp knitting, medical grade polyester knitting, and then medical polytetrafluoroethylene coating. The composite artificial blood vessels prepared are stable in structure and good in compliance, and are the main products in the current market. The histological structure of the hernia patch is mainly the warp knitted grid structure, which has the characteristics of large aperture and lightweight. The artificial ligament has an excellent repair effect on the treatment of tendon and ligament rupture. At present, the medical artificial ligament uses full width weft lining and chain knitting to change the warp knitting structure, which has low longitudinal and transverse elongation, high tensile strength and satisfactory fatigue resistance.
