Method for preparing high temperature furnace used carbon/carbon composite material cylinders

The invention discloses a method for preparing high temperature furnace used carbon/carbon composite material cylinders, which comprises the following steps: preparing carbon fiber rubberized cloth by dipping carbon fiber sheet in high-temperature phenolic resin of a rubber dip machine; controlling the winding tension of the carbon fiber rubberized cloth by a tension controller; pressurizing and solidifying the wound product after product winding; carbonizing the product; carrying out densification supplement according to the density of the product selectively; processing the product at a high temperature according to the service conditions of the high temperature furnace to adjust the comprehensive performance of the product; and mechanically processing the product according to a drawingto obtain a high temperature furnace used carbon/carbon composite material cylinder product. Adopting the processes, such as carbon cloth steak winding, pressurizing, solidifying and the like, the method has the advantages th
