Abstract

The invention discloses a preparation method of a high-density multi-angle woven carbon fiber carbon carbon barrel. The preparation method particularly comprises the following steps: cutting carbon fiber, carding into broken filaments by a carding machine and preparing into a net tyre; needling the single-layer net tyre and one-way arranged carbon fiber filaments into a unit layer with a needlingmethod; mutually intersecting the two unit layers and paving and needling into a composite carbon fiber pre-needling layer; winding the composite carbon fiber pre-needling layer on a supporting net grinding tool to form needling fiber in the direction from minus 90 degrees to 90 degrees; performing internal one-way glue spraying on an embryoid body with a high-permeability mist spraying method; and sequentially performing hot pressing, carbonization and purification on the glue-permeated material to obtain a carbon fiber heat-insulating cylinder primary product, and performing machining to prepare products needed by a high-temperature furnace. The density of the product is 1.1 to 1.8 g / cm<3>, heat-insulating resistance service life is long, the carbon fiber content is high, the service life is increased by 10 to 30 percent and the continuous production period is prolonged; and the use environment is wide.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation equipment, and in particular relates to a method for preparing a high-density multi-angle braided carbon fiber carbon cylinder. Background technique [0002] In the stage of high-speed development of high-temperature equipment, such as photovoltaic monocrystalline silicon growth furnaces, heat treatment furnaces, purification furnaces, etc. Due to the increase in demand, the product profit is low, and various domestic costs have increased. As one of the consumable parts, high-temperature-resistant containers and high-temperature-resistant structural materials consume a huge amount every year, and their service life directly affects the performance of enterprises. [0003] At present, most high-temperature-resistant containers and high-temperature-resistant structural materials in the market are produced by vapor deposition. The vapor deposition method has a long production cycle, low ...
