Embodiment 1
[0029] This embodiment is to manufacture a certain type of aircraft carbon ceramic brake disc-moving disc, and its specific process is as follows:
[0030] Step 1, preparing a carbon fiber green body;
[0031] The specification of the carbon fiber body is Φ312mm×Φ192mm×26mm, and the quantity is 15 pieces. Choose 12K carbon fiber, use latitude-free unidirectional carbon cloth and carbon fiber mesh tire to compound, lay the laminate with the direction of carbon cloth fiber at 0° / 60° / 120°, and form a carbon fiber green body of aircraft carbon ceramic brake disc-moving disc. The paving thickness of the carbon fiber green body is 25mm, and 16 layers / cm are guaranteed, and the bulk density is 0.6g / cm3.
[0032] Step 2, prepare C / C body
[0033] The prepared 15 pieces of carbon fiber blanks of aircraft carbon ceramic brake discs and moving discs were loaded into a CVI furnace for deposition. The deposition temperature was 1020°C. The deposition gas is natural gas and ethane, wher...
Embodiment 2
[0048] This embodiment is to manufacture a certain type of aircraft carbon ceramic brake disc-static disc, and its specific process is as follows:
[0049] Step 1, preparing a carbon fiber green body;
[0050] The specification of the carbon fiber body is Φ312mm×Φ192mm×25mm, and the quantity is 12 pieces. Choose 12K carbon fiber, use latitude-free unidirectional carbon cloth and carbon fiber mesh tire to compound, and lay the laminate in the direction of carbon cloth fiber at 0° / 60° / 120° to form a carbon fiber green body of aircraft carbon ceramic brake disc-stationary disc. The paving thickness of the carbon fiber green body is 20mm, and 15 layers / cm are guaranteed, and the bulk density is 0.6g / cm3.
[0051] Step 2, prepare C / C body
[0052] The prepared 15 pieces of aircraft carbon-ceramic brake disc-stationary disc carbon fiber blanks were loaded into a CVI furnace for deposition. The deposition temperature was 1000°C. The deposition gases are natural gas and ethane, wh...
Embodiment 3
[0067] This embodiment is to manufacture a certain type of aircraft carbon ceramic brake disc-pressing disc, and its specific process is as follows:
[0068] Step 1, preparing a carbon fiber green body;
[0069] Step 1, preparing a carbon fiber green body;
[0070] The specification of the carbon fiber body is Φ312mm×Φ192mm×25mm, and the quantity is 12 pieces. Choose 12K carbon fiber, use latitude-free unidirectional carbon cloth and carbon fiber mesh tire to compound, and lay the laminate in the direction of carbon cloth fiber at 0° / 60° / 120° to form a carbon fiber green body of aircraft carbon ceramic brake disc-stationary disc. The paving thickness of the carbon fiber green body is 15mm, and 14 layers / cm are guaranteed, and the bulk density is 0.6g / cm3.
[0071] Step 2, prepare C / C body
[0072] The prepared 15 pieces of aircraft carbon-ceramic brake disc-stationary disc carbon fiber blanks were loaded into a CVI furnace for deposition. The deposition temperature was 101...
