Embodiment 1
[0032] A method for weaving a carbon fiber prefabricated body of an automobile brake disc. The prepared carbon fiber prefabricated body is in the shape of a ring, with an outer diameter of 392mm, an inner diameter of 143mm, and a thickness between the upper and lower sides of 43mm. The weaving method includes:
[0033] (1) Preparation of carbon fiber plain weave; carbon fiber plain weave is prepared from Japan Toho HTS40-3K carbon fiber silk, Japan Toho HTS40-3K carbon fiber silk is untwisted polyacrylonitrile long carbon fiber silk, and the preparation process is warp direction carbon fiber and weft Interweave every other strand of carbon fiber to form a plain weave structure, such as figure 2 As shown, the carbon fiber plain weave is obtained;
[0034] (2) Preparation of carbon fiber mesh tires; carbon fiber mesh tires are prepared from Japanese Toray T700SC-12000-50C untwisted polyacrylonitrile chopped carbon fibers, and the length of chopped carbon fibers is 60-70mm;
