Carbon nano tube deposited carbon-carbon composite material
The invention provides a preparation method of a carbon nano tube deposited carbon-carbon composite material. The preparation method comprises the following steps: preparing carbon fiber cloth with deposited carbon nanotubes; coating the mixed adhesive on the surface of the carbon fiber cloth on which the carbon nanotubes are deposited; placing the surface-dried carbon fiber cloth in a carbonization furnace, and carrying out carbonization treatment; and heating the densified preform to 1000 DEG C at the rate of 300-350 DEG C/h in an argon atmosphere, then respectively heating to 2500 DEG C at the rate of 300-350 DEG C/h, and keeping the constant temperature for 0.5-1 hour to obtain the carbon nano tube deposited carbon-carbon composite material. According to the carbon-carbon composite material, the short carbon fibers are embedded in the carbon matrix and the carbon fibers, and the carbon nanotubes are deposited between the carbon matrix and the carbon fibers, so that the mechanical property of the carbon-carbon composite material is remarkably improved, meanwhile, graphite is utilized to load phosphate in the carbon matrix, so that the oxidation resistance of the material can be remarkably improved; meanwhile, the phosphate is loaded on the graphene which is consistent with the matrix in performance, so that the mechanical property of the material is almost not influenced.
本发明提供一种沉积碳纳米管的碳碳复合材料的制备方法，包括以下步骤：积碳纳米管的碳纤维布的制备；将混合胶粘剂涂覆于沉积碳纳米管的碳纤维布表面；表干后的碳纤维布置于碳化炉中，碳化处理；致密化的预制体于氩气气氛下以300‑350℃/h的速率升温至1000℃，再以300‑350℃/h的速率分别升温至2500℃，恒温0.5‑1h，即得沉积碳纳米管的碳碳复合材料。本发明提供的碳碳复合材料在碳基体和碳纤维内嵌入短切碳纤维，并在碳基体和碳纤维之间沉积碳纳米管，显著提高了碳碳复合材料的力学性能，同时利用石墨在碳基体内部负载磷酸盐，可显著提高材料的抗氧化性能，同时因磷酸盐负载在与基体性能一致的石墨烯上，对材料的力学性能几乎无影响。
