Embodiment 1
[0036] This embodiment includes the following steps:
[0037] Step 1. Set the density to 0.50g / cm 3 The needle-punched non-weft carbon cloth integral carbon disc preform is loaded into a high-temperature heat treatment furnace, and subjected to high-temperature pretreatment at a temperature of 1800 ° C; the needle-punched non-weft carbon cloth integral carbon disc preform is composed of carbon fiber plain cloth and carbon The fiber mesh tires are alternately layered and made by radial needle punching;
[0038] Step 2, the needle-punched non-weft carbon cloth integral carbon disc preform after high temperature pretreatment in step 1 is loaded into a vapor deposition furnace with a diameter of 600 mm, and the furnace loading structure is as follows: figure 1 As shown, the needle-punched non-weft carbon cloth integral carbon disc preform 4 after high temperature pretreatment is loaded into the furnace chamber surrounded by the heating element 2 of the vapor deposition furnace to...
Embodiment 2
[0043] This embodiment includes the following steps:
[0044] Step 1. Set the density to 0.70g / cm 3 The needle-punched non-weft carbon cloth integral carbon disc preform is loaded into a high-temperature heat treatment furnace and subjected to high-temperature pretreatment at a temperature of 2400 ° C; the needle-punched non-weft carbon cloth integral carbon disc preform is composed of carbon fiber twill cloth and carbon fiber The mesh tires are alternately layered and made by radial needle punching;
[0045] Step 2: Put the needle-punched non-weft carbon cloth integral carbon disc preform after high temperature pretreatment in step 1 into a vapor deposition furnace with a diameter of 650 mm, and put the needle-punched non-weft carbon cloth as a whole after high temperature pretreatment. The carbon disc preform 4 is loaded into the furnace chamber surrounded by the heating element 2 of the vapor deposition furnace to form a single material column. The top of the single materi...
