     (1) Preparation of composite three-dimensional reinforced base mesh. In order to produce the reinforced base mesh used in the ellipsoidal three-dimensional composite material, the warp and weft yarns used in the weaving process must have a specific length. To this end, they carried out secondary development of the existing warp let-off and weft insertion system, including a warp let-off module and a weft insertion module used to adjust the length of the weft in sections. The project developed a numerical control device and a flexible adjustment device to adjust the length of the weft yarn that needs to be maintained to form a specific shape in each gap of the braid. Finally, after weaving and forming on a multi-axis warp knitting machine, concrete is poured using this as a base net to produce the displayed ellipsoidal textile-based concrete object.

      (2) Metal fiber spun yarn with unique structure. In order to explore the large-scale application potential of pure metal yarns in high-tech fields as much as possible, the project developed a cost-effective and high-performance 100% metal staple fiber yarn, which realized the spinning of metal fibers made by scraping aims. The metal fiber spun yarn is finally produced through the steps of bundle breaking, drafting and scraping. In the spinning process, the high abrasion resistance, brittleness and stiffness of the fiber are taken into consideration, which avoids the restriction of these special properties of metal fibers on the production process. In addition, in order to realize the large-scale application of the metal yarn in the high-tech field, the project also compounded the metal yarn and the thermoplastic filament yarn, and finally developed a metal matrix composite material.

     (3) Hybrid tow spreading device. The development of this device makes it possible to produce mixed fiber intermediate products (≥90 g/m²). Carbon fiber composites of carbon fiber bundles (3300tex), glass fiber bundles (2400tex) and PP and PA6 were produced on the ITM experimental machine. The modular fiber spreading device allows adjustment of fiber volume content and expansion coefficient (up to five times). Therefore, multifunctional fiber belts with a width of up to 100 mm can be made from a single roving, and further tests can be performed to verify the production applicability of the fiber spreading device. Compared with the traditional fiber tape production process, the fiber spreading device is a low-cost alternative. This technology greatly expands the production potential of fiber-reinforced composite materials.
