3D weaving: smart reinforcement of composite materials
Traditional polymer composite materials have a reinforcing structure that resembles a "layered cake" of reinforcing fibers arranged in a single plane. This structure inevitably leads to material delamination during use or due to impact. This problem significantly limits the potential applications of conventional composite products when higher requirements are needed. A solution is the use of three-dimensional woven reinforcing frameworks, which are manufactured on a specialized 3D weaving machine. This technology is called 3D weaving.
New Industry And Energy
New materials and substances
The technology is mature and ready for scalable implementation (TRL-9). Establishing production from scratch takes approximately one year, encompassing design, manufacturing, assembly, and commissioning of the "Carbontex" 3D weaving complex.
The technology's implementation is most suitable in regions with established composite industries and a thriving market for composites. This includes areas with strong aerospace, shipbuilding, automotive, high-rise construction, and other related industries. The raw materials for composite production, such as resins and synthetic fibers, are sourced from the chemical industry and should be readily available.
Unlike traditional composite manufacturing methods, 3D weaving enables: 1. Delamination-free materials: Eliminating the inherent weakness of layered composites. 2. Enhanced impact resistance: Resulting in materials 5-7 times stronger against impact. 3. Complex geometry: Creating intricate, single-piece reinforced structures like aircraft engine blades or propeller blades. 4. Increased automation: Through the use of a 3D weaving machine. 5. Improved accuracy: Reducing reliance on manual labor and enhancing precision.
