C/C composite CVD densification furnace for nozzle engine throat




CVD (Chemical Vapor Deposition) One or more controlled carbon source gases are pyrolyzed through the gas distribution plate set in the CVD furnace, and flow through the carbonized resin-reinforced carbon fiber matrix in a low vacuum state to fill the voids of the matrix material, and further carbonize to increase the density. Long-term Heat treatment causes the carbon to form larger graphite crystals, resulting in higher performance carbon-carbon composites. A variety of gases with higher requirements flow into the heated base material in the furnace in turn, and the temperature, pressure, flow rate, and carrier gas volume are precisely controlled to obtain single-layer graphene on the surface of the base material. The temperature, pressure, gas flow rate, gas ratio and cooling rate during the reaction will all have an impact on the quality and layer thickness of material.
Chenxin Horizontal CVD furnace, features simple working principle compared to vertical series. The main advantages of horizontal design are easy loading/unloading, easy clean-up of furnace inside, simple operation and maintenance for workers, and easy replacement of consumable spare parts.
one or more Controlled carbon source gases are cracked at high temperature, and the pyrolytic carbon is deposited in the void of the preform, and gradually forms larger graphite crystals, thereby forming a high-strength carbon fiber reinforced carbon-carbon composite material
Application:
Applications: rocket nozzle densification, engine throat densification, etc.
