Even controllable carbon-carbon composite aspect has potentiality.But, in using isothermal CVD technique preparation process, pyrolytic carbon can be excellent
The surface of precast body is first deposited to, precast body surface hole is closed too early, affect its internal density, it usually needs using low
Warm, low gas concentration opens hole to reduce reaction speed and multiple machining removal surface crust, thus prepares highly dense
, up to one month or even some months, manufacture efficiency is low, high cost for the manufacturing cycle of degree carbon-carbon composite.
At present, the technique for preparing carbon-carbon composite also has a kind of thermograde CVD technique, this thermograde CVD work
Skill is the improvement to traditional isothermal CVD techniques.In this process equipment, prefabricated internal temperature distribution gradient, presoma leads to
Cross diffusion mass transfer and reach high-temperature region from low-temperature space and deposit, pyrolytic deposition area by Inside To Outside iterative method, with tradition etc.

Empty autoclave, with nitrogen as protective gas, first under vacuum with maceration extract impregnation of carbon fibers precast body or low-density C/C base
Body workpiece, then maceration extract is permeated to inside workpiece under the conditions of nitrogen pressure, it is then isobaric to reclaim unnecessary maceration extract, continue
Equipressure heats up makes resin thermosets, then is carbonized to fill the carbon base body of inside workpiece hole.Aforesaid operations circulation is carried out several times
The carbon/carbon compound material component of density required for obtaining.Impregnation pressure needed for the method would generally reach 5MPa, when blank density is got over
When coming higher, the less and less required impregnation pressure of porosity in base substrate can be bigger；Very high to impregnating equipment requirement, equipment also compares
It is more complicated, production equipment costly, while operating than relatively hazardous because pressure is excessive.
