Device for preparing carbon-carbon composite material
The invention discloses a device for preparing a carbon-carbon composite material, and relates to the technical field of new material preparation. In the device, a preform is arranged in a tool, a heater is arranged on the outer portion of the tool, a gas inlet pipe (12) is arranged on the lower portion of the tool, an exhaust pipe (1) is arranged on the upper portion of the tool, gas is conveyed from inside to outside, deposition of pyrolytic carbon is propelled from high temperature to low temperature to complete densification, and therefore the deposition rate is increased, the density uniformity is ensured, surface crusting of the preform is effectively avoided, one-step molding of the preform can be realized, and the device has the characteristics of being high in deposition efficiency, good in product performance, large in development potential and the like and is suitable for large-scale popularization and application.
一种制备碳碳复合材料的装置，涉及新材料制备技术领域，本发明中预制体设置在工装内，在工装的外部设置加热器，在工装的下部设置进气管（12），在工装的上部设置抽气管（1），气体由内向外输送，热解碳的沉积由高温向低温推进完成致密化，从而提高沉积速率，保证密度的均匀性，有效的避免了预制体表面结壳，可以实现预制体的一次成型等，本发明具有沉积效率高、制品性能好，发展潜力大等特点，适合大范围的推广和应用。
