Special-shaped curved surface quasi-triaxial fabric, knitting process method thereof and application of fabric

The invention discloses a special-shaped curved surface quasi-triaxial fabric, a knitting process method thereof and an application of the fabric. The method includes the steps: 1) designing and manufacturing a core mold with a hollow structure according to the appearance of the fabric and forming a plurality of needle holes in the core mold; 2) threading normal fibers at the tails of steel needles, enabling the tip of each steel needle to penetrate one needle hole outwards from the inside of the core mold and retaining the tails in the needle holes; 3) winding warp-wise fibers and weft-wise fibers in gaps of the steel needles on the outer surface of the core mold, and knitting warp-wise and weft-wise fiber layers; 4) pulling out the steel needles one by one, reserving the normal fibers inthe fiber layers, pressing the fiber layers by a prepressing tool and releasing the mold to obtain the special-shaped curved surface quasi-triaxial fabric when the warp-wise fibers and the weft-wisefibers reach specified thi
