Graphite sagger production process
The invention discloses a graphite sagger production process which comprises the following steps: S1, material preparation: selecting a chopped carbon fiber reinforced graphite-based composite material as a material A, and selecting a continuously woven carbon fiber reinforced graphite-based composite material as a material B; s2, performing a mold pressing process: performing mold pressing molding on the raw materials in percentage by weight: 15-25% of the material A and 75-85% of the material B in a spreading manner; s3, a carbonization process: carrying out high-temperature carbonization on the molded product at a certain temperature; s4, a gum dipping process: performing gum dipping on the molded product to repair defects, dipping the product in phenolic resin for more than one hour under a vacuum suction condition, taking out the product, and scraping off the resin on the surface of the product; s5, performing a secondary carbonization process: performing secondary high-temperature carbonization on the product subjected to gum dipping; and S6, detecting and packaging. According to the graphite sagger production process, the chopped carbon fiber reinforced graphite-based composite material and the continuously woven carbon fiber reinforced graphite-based composite material are alternately laid to form the graphite sagger, and the stress strength of the graphite sagger can be guaranteed after compression molding.
本发明公开了一种石墨匣钵生产工艺，包括以下步骤：S1、材料准备：选用短切碳纤维增强石墨基复材作为A料，选用连续编制碳纤维增强石墨基复材作为B料；S2、模压工艺：原料以重量百分比计，将A料15％—25％、B料75％—85％，以铺料方式模压成型；S3、碳化工艺：将成型制品以一定的温度高温碳化；S4、浸胶工艺：将成型制品浸胶修补缺陷，将制品在吸真空条件下，浸渍于酚醛树脂中，浸渍一小时以上，取出刮去表面树脂；S5、二次碳化工艺：将浸胶后的制品二次进行高温碳化；S6、检测和包装。该石墨匣钵生产工艺采用短切碳纤维增强石墨基复材和连续编制碳纤维增强石墨基复材交替铺料构成石墨匣钵，在压制成型之后能够保证石墨匣钵的受力强度。
