Custom CFC Carbon-Carbon Composite Profiles
High-Temperature Structural Stability
CFC carbon-carbon composite profiles maintain strength and shape up to 2,000°C in vacuum or inert atmospheres, keeping door edges and hot-zone frames stable during long heat cycles.
Lightweight Strength & Low Expansion
Exceptional strength-to-weight ratio with very low thermal expansion reduces load on hinges and mechanisms while preserving sealing gaps and dimensional accuracy.
Thermal Shock Resistance & Long Service Life
Fiber-reinforced carbon matrix resists cracking under rapid heating/cooling, extending service intervals versus metal or monolithic graphite parts and lowering lifetime cost.
Custom Profiles & Tight Tolerances
Available in L-, U-, step-edge and corner forms; CNC-machined to drawing with typical tolerances to ±0.1 mm for precise door-edge interfaces and repeatable installation.
Clean Operation & Broad Compatibility
Low particle shedding and chemically clean surfaces support high-purity processes; fits most major vacuum furnace brands and integrates with existing sealing and fastening systems.
Description
Custom CFC Carbon-Carbon Composite Profiles for Vacuum Furnace
SHJ CARBON designs and manufactures CFC (Carbon-Carbon Composite) profiles specifically for vacuum furnace door edge protection and other high-temperature applications. With strong engineering experience in graphite and carbon materials, we help customers improve furnace performance, extend service life, and reduce downtime through advanced carbon composite solutions.
High-Performance Carbon Composite for Extreme Temperatures
CFC-also known as carbon-fiber-reinforced carbon-offers unmatched high-temperature resistance up to 2000 °C.
It maintains structural integrity under rapid heating and cooling, minimizing distortion inside the vacuum furnace hot zone.
The material's low thermal expansion, lightweight, and impact-resistant characteristics make it ideal for door edges, support frames, and internal brackets.
Customizable U-Shape and L-Shape Profiles
- Every furnace structure is unique, and SHJ CARBON supports complete customization.
- We produce U-shaped, L-shaped, and bespoke CFC profiles to match specific furnace door dimensions.
- You can define length, thickness, and cut geometry, and our engineering team will provide a drawing and sample before production.
- We also integrate graphite components or carbon felt insulation when clients need a full thermal management solution.
Real Case: CFC Door Edge Retrofit in a Vacuum Furnace
A European furnace manufacturer faced repeated deformation and cracking in its traditional steel door frame. This project demonstrates how CFC carbon composite materials outperform conventional metals and graphite under extreme furnace conditions. It also shows our ability to custom-engineer U-shape and L-shape CFC profiles for complex furnace geometries.

FAQs for CFC Carbon-Carbon Composite Profiles
CFC (Carbon Fiber Reinforced Carbon) profiles are primarily used around the door edge and hot-zone structure of vacuum furnaces to provide thermal insulation, mechanical strength, and dimensional stability. Their high temperature resistance and lightweight design prevent deformation under repeated heating and cooling cycles.
Unlike solid graphite or metal components, CFC composites combine strength, low density, and superior thermal shock resistance. They do not warp, crack, or oxidize easily under high temperature gradients, making them ideal for furnace door frames, support edges, and structural reinforcement parts.
Our CFC carbon-carbon composite profiles are designed for continuous use up to 2000°C in vacuum or inert atmospheres. The exact service temperature depends on the density, fiber orientation, and matrix treatment process selected for your furnace type.
