BZN Carbon specializes in the production of high-quality carbon carbon composite plates, designed for demanding industrial applications requiring exceptional thermal and mechanical performance. Our C/C composite plates are engineered using advanced fiber architecture—including 2D, 2.5D, 3D, and 4D reinforcements—to ensure optimized strength, dimensional stability, and service life at extreme temperatures.

We offer custom manufacturing based on client drawings and application requirements, including a variety of size and density combinations. Standard size options range from 10 mm to 600 mm in width/length, with thicknesses from 5 mm to 60 mm. Special dimensions and profiles can be tailored on request.

What Are Carbon Carbon Composite Plates?

Carbon carbon (C/C) composite plates are engineered materials formed by reinforcing carbon or graphite matrices with carbon fibers or fabrics. These composites are produced through a high-temperature process involving resin or pitch infiltration followed by carbonization and optional graphitization. The result is a lightweight yet ultra-strong plate capable of operating in harsh, high-temperature environments.

Key Features and Advantages

Exceptional Thermal Resistance: Capable of withstanding continuous use at temperatures exceeding 2500°C in inert or vacuum environments.
Lightweight with High Strength: Lower density compared to metal alloys, yet excellent flexural and compressive strength.
Superior Thermal Shock Resistance: Withstands rapid temperature changes without cracking or deformation.
Excellent Chemical Inertness: Resists corrosion from acids, alkalis, and salts; suitable for high-purity environments.
Customizable Structure and Density: Manufactured with different weave types and densities based on the application.
