Preparation method of carbon-carbon composite material
The invention belongs to the technical field of carbon materials, and particularly relates to a preparation method of a carbon-carbon composite material. The preparation method of the carbon-carbon composite material provided by the invention comprises the following steps: (1) pre-dipping and coating carbon fiber cloth with a resin mixed solution, and then carrying out curing treatment to obtain a carbon fiber prepreg; the resin mixed solution comprises phenolic resin, a filler, a coupling agent, an accelerant and an organic solvent; (2) laminating the carbon fiber prepreg to construct a multi-layer structure, pressing, and carbonizing an obtained resin-based blank to obtain a carbonized body; and (3) sequentially and repeatedly carrying out the steps (1) and (2) on the carbonized body, and carrying out graphitization treatment to obtain the carbon-carbon composite material. According to the method, the compatibility between the resin and the carbon fiber matrix and the wettability of the resin in the carbon fiber can be improved, and the strength and heat resistance of the carbon-carbon composite material are improved, so that the carbon-carbon composite material is not layered in the carbonization and graphitization processes, and the product yield is improved.
本发明属于碳材料技术领域，具体涉及一种碳碳复合材料的制备方法。本发明提供的碳碳复合材料的制备方法，包括以下步骤：(1)将碳纤维布通过预浸涂覆树脂混合液后，进行固化处理，得到碳纤维预浸料；所述树脂混合液包括酚醛树脂、填料、偶联剂、促进剂和有机溶剂；(2)将所述碳纤维预浸料叠层构筑多层结构后，进行压合，所得树脂基坯体进行碳化处理，得到碳化体；(3)将所述碳化体依次重复进行步骤(1)和(2)后，进行石墨化处理，得到碳碳复合材料。该方法能改善树脂与碳纤维基体之间的相容性和树脂在碳纤维中的浸润性，提高碳碳复合材料的强度和耐热性能，使其在碳化、石墨化过程中不分层，从而提高产品良率。
