Method for producing unidirectional hybrid-braided fabrics

A method for producing unidirectional hybrid-braided fabrics, comprising

• step 1:
• preparing a first layer of 0° warp yarns (1);
• step 2:
• preparing a second layer of 0° warp yarns (2) to a Nth layer of 0° warp yarns, wherein N is a natural number greater than or equal to 2;
• step 3:
• preparing an auxiliary layer of weft yarns (3);
• step 4:
• preparing binding yarns (4);
• step 5:
• laying the first layer prepared in step 1 directly onto the second layer prepared in step 2, laying the second layer directly onto the auxiliary layer prepared in step 3, and hybrid-braiding the first layer, the second layer and the auxiliary layer with the binding yarns of step 4 to obtain unidirectional hybrid-braided fabrics;
• and
• step 6:
• cutting and winding;
• wherein the first layer of warp yarns, the auxiliary layer of weft yarns, and the Nth layers of 0° warp yarns are of different materials,
• wherein in the step 3, the auxiliary layer of weft yarns (3) are laid at an angle of 90°, ±M°, or at multiple angles, wherein M>0,
• wherein the first layer of 0° warp yarns (1), the second layer of 0° warp yarns (2) to the Nth layer of 0° warp yarns, and the auxiliary layer of weft yarns (3) are selected from the group consisting of glass fiber, carbon fiber, basalt fiber, aramid fiber, ultra-high molecular weight polyethylene fiber, polyamide fiber, polyphenylene sulfide fiber, polyimide fiber, polyester fiber, polypropylene fiber and nylon fiber, the warp yarns and weft yarns being of different materials,
• wherein the first layer of 0° warp yarns (1) and the second layer of 0° warp yarns (2) to the Nth layer of 0° warp yarns are of different materials,
• wherein two or more of the first layer of 0° warp yarns (1) and the second layer of 0° warp yarns (2) to the Nth layer of 0° warp yarns whose grammages account 90% or more are laid in a single direction and hybrid-braided, and
• wherein the first layer of 0° warp yarns (1) and the second layer of 0° warp yarns (2) to the Nth layer of 0° warp yarns have a grammage of between 30 to 3,000 grams/m2.
