Process Caracteristics
The rolling process is made by using twill or unidirectional carbon fiber prepreg layer by layer wound on a metal mandrel and then cured at high temperature. During this process, the quality control of the tube is mainly carried out in two aspects: first, to ensure that the size of the metal mandrel must be accurate and appropriate, because the carbon fiber prepreg is wound on the outside of the mandrel, and the outer diameter of the mandrel itself needs to match the inner diameter of the carbon fiber tube manufactured; second, the layering scheme of the wound carbon fiber prepreg is carefully designed. The number and thickness of the carbon fiber prepreg wound on the mandrel determines the outer diameter of the carbon fiber tube. The fibers of the woven carbon fiber prepreg are oriented at the 0° axis (down the length of the tube) and the 90° axis (around the circumference of the tube). These layers add the so-called hoop strength to the tube, making it less susceptible to extrusion or bursting forces, while the unidirectional prepreg on the 0° axis can mainly improve the longitudinal stiffness of the tube.
Stable Product Performance: The resin content of carbon fiber tubes produced by the rolling process is relatively stable, which can effectively solve the problems caused by uneven temperature during the curing process.
High Production Efficiency: The molding speed is faster, which is conducive to mass production. Continuous layering can save time and cost and improve production efficiency.
Strong Applicability: The rolling process can produce carbon fiber tubes with longer lengths and larger diameters, which can meet the requirements of tube sizes in different fields.
