With the upgrading of global high-end equipment manufacturing technology, traditional synthetic graphite has gradually failed to meet the extreme performance requirements of ultra-high temperature, high load and strong ablation. Carbon-carbon (C/C) composite graphite components, as a new generation of advanced carbon materials, are formed by carbon fiber reinforcement and graphite matrix composite molding. Compared with ordinary graphite, C/C composite graphite has ultra-high specific strength, ultra-low density, excellent anti-ablation performance and fatigue resistance, and is the core material for extreme working conditions such as aerospace ultra-high-speed flight, industrial ultra-high-temperature sintering and high-load thermal equipment.
The fundamental performance advantages of carbon-carbon composite graphite come from its composite structure. Traditional graphite is a single matrix material with poor tensile strength and easy brittle fracture under impact load; while C/C composite takes carbon fiber as the skeleton and graphite matrix as the filling layer, which perfectly combines the high toughness of carbon fiber and the high-temperature stability of graphite. Its density is only 1/4 of steel, but its high-temperature strength is far higher than that of metal materials, and it will not soften or creep at ultra-high temperature above 3000°C.
In the aerospace field, C/C composite graphite components are widely used in rocket engine tail nozzles, hypersonic vehicle thermal protection panels, aerospace brake discs and high-temperature test fixture components. The ultra-light weight of composite materials can effectively reduce the overall weight of aerospace equipment, improve load capacity and flight efficiency; excellent anti-ablation performance can resist long-term high-temperature flame scouring and airflow erosion, greatly extending the service life of reusable aerospace equipment. In satellite thermal control systems, low-density C/C composite heat conduction components realize efficient heat dissipation and lightweight structural integration.
In industrial ultra-high-temperature equipment, C/C composite graphite components are used in semiconductor crystal growth furnaces, high-temperature vacuum sintering furnaces and special material heat treatment equipment. Composite graphite heating elements and bearing fixtures have higher high-temperature structural stability than ordinary graphite, no deformation under long-term ultra-high temperature load, and longer service cycle. In the photovoltaic industry, customized C/C composite thermal field components can reduce the thermal inertia of the furnace body, accelerate temperature rise and fall speed, and improve the production efficiency of silicon wafers.
The processing and molding of carbon-carbon composite graphite components is more difficult than ordinary graphite. The composite material has high fiber toughness and is easy to produce burrs and delamination during cutting. It requires professional processing technology and special tools to ensure the dimensional accuracy and structural integrity of components. At the same time, surface anti-oxidation coating treatment is required for composite graphite used in aerobic high-temperature environment to further improve its service performance.
