Abstract
The invention belongs to the field of fabric weaving methods, in particular to a method for producing a multi-axial reinforcing fabric with special-angle layering. The method comprises the following steps: carrying out a first weave by way of respectively laying the reinforcing fibers along a zero-degree direction, a negative direction and a 90-degree direction so as to bundle and weave the fibers into a first reinforcing fabric according to a weave method of tricot stitch or extended tricot stitch; then carrying out a second weave by way of laying the reinforcing fibers along a positive direction and a 90-degree direction and lining the first reinforcing fabric below the positive reinforcing fibers and the 90-degree reinforcing fibers so as to bundle and weave the fibers into a multi-axial reinforcing fabric that the zero-degree reinforcing fibers are arranged between the positive reinforcing fibers and the negative reinforcing fibers according to a weave method of warp chain stitch. The method disclosed by the invention has the advantages that because the multi-axial reinforcing fabric with special-angle layering is weaved trough a two-step weave method, the method meets the customer needs and is high in production efficiency and low in cost, thereby realizing good economic benefits; and the prepared fabric is high in strength, good in toughness, and long in service time.
