CFC Crucible

What is Carbon Fiber Composite?

Carbon fiber-reinforced carbon (C/C) or carbon fiber composite is a high-strength composite consists of a carbon or graphite matrix, that is fortified with very strong carbon fibers. Carbon Fiber Composite is also referred to as Carbon-Carbon Composite, CFC, or Carbon Reinforced Matrix Composite. All of these aliases refer to this product.

Our CFC parts

Our CFC parts include but are not limited to: Sheets, Angles, U-Channels, Rings, Tubes, Pipes, Cylinders, Bolts, Screws, Nuts, Threaded rods, Washers, Heating Elements, Shelving, Survey Racks and Baskets for heat-treating.

CFC Threaded rods, bolts and nuts

C/C-composite Bolts & Nuts characterized by its high heat resistance are used in many high temperature environments over 1000°C while metals or ceramics lose mechanical strength.

Also, the unique graphite properties such as resistance to adhesion or friction make them ideal for joining components under high temperatures.

CFC Cylinders

We deliver CFC cylinders in an excellent quality for high temperature applications such as hot pressing of tungsten carbide or ceramics.

Carbon-carbon composite features:

(1) Physical properties: After high temperature treatment, the carbon composite has higher carbon content, >99%, the density is low, the mechanical properties are good. Due to good characteristic of high melting point of carbon, high temperature resistance, corrosion resistance and thermal shock performance, the carbon composite is resistant to acid, alkali and salt.

(2) High mechanical strength: the strength is 5 times that of steel at high temperature.

(3) High temperature resistance: excellent mechanical and electrical properties can still be maintained at temperatures above 2000ºC.

(4) Low thermal expansion coefficient.

(5) Low heat capacity. Special Properties of carbon carbon composite: High Acid-resisting and alkali-resisting properties; Low density compared to metals; High temperature, cold-resistant, tensile strength is 7-9times than Steel; very good thermal shock resistance.
