  • Patent number: 11286592
    Abstract: The present invention discloses a method for producing unidirectional hybrid-braided fabrics, including: preparing a first layer of 0° warps; preparing a second layer of 0° warps to a Nth layer of 0° warps; preparing an auxiliary layer of wefts; preparing binding yarns; laying and hybrid-braiding the materials prepared in steps 1-4 to obtain unidirectional hybrid-braided fabrics; and cutting and winding. The 0° warps and wefts of the invention are made of two or more layers of different fibers that are laid in a single direction and finally hybrid-braided. Therefore, two or more different types of materials can be laid, thereby ensuring the uniform distribution and thickness of the fibers in different areas of the hybrid-braided fabric. The grammage of different 0° warp fiber layers can be adjusted freely in a range of 30-3000 grams/m2, thereby realizing performance and cost designability of a composite material.
