Carbon Carbon Composite U & L Profiles
Explore BZN Carbon’s carbon carbon composite U and L profiles, engineered for high-temperature applications in silicon and furnace systems. Custom dimensions available.
Description
BZN Carbon designs and manufactures high-performance carbon carbon composite U profiles and L profiles for demanding thermal environments. Engineered with 2D and 2.5D carbon fiber architectures, these components offer superior strength-to-weight ratio, thermal resistance, and dimensional stability — ideal for polycrystalline silicon furnaces and other high-temperature applications.
Each profile is manufactured with precision, using custom shapes, dimensions, and densities based on your design specifications.
What Are Carbon Composite U and L Profiles?
These are specially shaped carbon-carbon composite components made from layers of carbon fiber woven in 2D or 2.5D configurations. The resulting U and L profiles are lightweight, extremely heat resistant, and exhibit minimal thermal expansion — making them ideal for use as structural or heating support elements within furnace systems.
Applications
Photovoltaic industry: polycrystalline silicon ingot furnaces, Czochralski silicon growth equipment
Semiconductor manufacturing: heating systems, insulation brackets
Heat treatment and metallurgy: support and structural parts exposed to extreme thermal cycling
Advanced material research: vacuum furnaces, carbon-carbon thermal chambers
Key Advantages
Low mass and high mechanical strength
Resistant to thermal shock and oxidation (in inert atmosphere)
Customizable in size, length, and thickness
Extended lifespan under extreme processing temperatures
Cost-effective alternative to traditional graphite or ceramic profiles
