In the above production process, the mandrel is a very important tool. The size of the mandrel is not appropriate, and the carbon fiber tube produced cannot meet the demand. Small-caliber carbon fiber round pipes require special customized small-caliber core molds, which impose high technical requirements on mold manufacturers.
In addition, the smaller the diameter of the carbon fiber tube, the more likely it is that there will be problems in the production process, such as delamination fracture, etc., which requires higher production equipment and personnel experience for carbon fiber manufacturers. Therefore, this parameter can also reflect the strength of carbon fiber manufacturers. At present, Zhishang New Material can produce carbon fiber tubes with a caliber ranging from 6 to 450mm, the length can reach 4.5 meters, and the thickness can be as low as 1mm.
