Abstract
Description
Technical Field
[0001] The invention relates to the field of weaving, in particular to the field of carbon fiber weaving technology, and specifically refers to a carbon fiber triaxial high-strength three-dimensional effect fabric and a weaving method thereof. Background Art
[0002] Due to its excellent performance, carbon fiber fabric is widely used in high-end products in the sports field and the aerospace industry. Traditional carbon fiber flat fabric is formed by two groups of mutually perpendicular yarns in two axial directions interwoven on the same surface. It has strong tear resistance only along the direction of the yarn, and its ability to bear loads in most directions is weak. In addition, the warp and weft yarns woven along the two axes have a large curvature. When the fabric is loaded, it deforms greatly, and the friction between the warp and weft yarns is more frequent, which reduces the service life of the carbon fiber fabric. The patterns of existing carbon fiber fabrics are mostly flat, the products are single, and the three-dimensional effect cannot be achieved, which makes it difficult to meet the requirements of some users for three-dimensional patterns. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides a carbon fiber tri-axial high-strength three-dimensional effect fabric and a weaving method thereof, which is woven along three axes, thereby increasing the tear resistance of the carbon fiber fabric, reducing the curvature of the fiber bundle, reducing the deformation of the carbon fiber fabric, and extending the service life of the carbon fiber fabric.
