Carbon fiber wound crucible and preparation method thereof
The invention discloses a carbon fiber wound crucible and a preparation method thereof. The preparation method comprises the following steps: preparing a mold; preparing an adhesive; impregnating carbon fibers; preparing a first blank of a carbon fiber wound crucible; curing the first blank of the carbon fiber wound crucible; carbonizing the second blank of the carbon fiber wound crucible; carrying out dipping-carbonizing on the second blank of the carbon fiber wound crucible; graphitizing the second crucible blank wound by the carbon fibers; carrying out machining; and coating. According to the technical scheme, wound carbon fibers are used as a crucible reinforcing phase, so that the strength advantage of carbon fibers is fully played, and the service life of the crucible is prolonged; the winding efficiency is high, wherein two crucibles are combined for winding, and two crucible blanks can be obtained through winding; and the carbon/carbon composite material crucible prepared through the method is stable in structure, the density is larger than or equal to 1.2 g/cm<3> after one-time carbonization, the interlayer bonding strength is high, and the preparation period is short.
本发明公开了一种碳纤维缠绕坩埚及其制备方法，包括以下步骤：模具的制备；粘接剂的制备；碳纤维的浸渍；碳纤维缠绕坩埚第一毛坯的制备；碳纤维缠绕坩埚第一毛坯的固化；碳纤维缠绕坩埚第二毛坯的碳化；碳纤维缠绕坩埚第二毛坯的浸渍‑碳化；碳纤维缠绕坩埚第二毛坯石墨化；机加工；涂层；其技术方案要点是，该发明用缠绕的碳纤维作为坩埚增强相，充分发挥碳钎维的强度优势，提高了坩埚的使用寿命；缠绕效率高，采用两个坩埚组合进行缠绕，一此缠绕可得到两个坩埚毛坯；用本方法制备的碳/碳复合材料坩埚结构稳定，一次碳化后密度≥1.2g/cm3，层间结合合强度高，制备周期短。
