Ultrahigh-modulus biaxial fabric

The ultrahigh-modulus biaxial fabric comprises a plurality of fiber layers which are sequentially arranged from bottom to top, a plurality of reinforcing rib layers are arranged between every two adjacent fiber layers, and the included angle between fibers of every two adjacent fiber layers is 90 degrees. The included angle between the two reinforcing rib layers between the two fiber layers is 90 degrees, and the included angle between fibers of any reinforcing rib layer and the adjacent fiber layer is 45 degrees; and all the fiber layers and the reinforcing rib layers are woven into a whole. The mechanical property in the 45-degree direction, the smoothness of the fabric and the flow guide performance are emphatically highlighted, the mechanical property and process requirements of the fabric in the blade manufacturing process are met through the reasonable structure and the matching with the actual process, the axial strength of the fabric can reach 170 Mpa or above, the modulus can reach 14 Gpa or above, a
