OUR KEY TECHNOLOGY
Core Technology to Manufacture Carbon-Carbon and Carbon-Ceramic Composite
Lorem ipsum dolor sit amet consectetur adipiscing elit mauris molestie orci eget condimentum sollicitudin felis orci.
Carbon Densification
We have CVI (Chemical Vapor Infiltration), CVD (Chemail Vapor Deposition), and LPI (Liquid Phase Infiltration) proces to produce carbon carbon composite.
Ceramization
We covert carbon-carbon (C/C) composites into carbon-ceramic (C/C-SiC) composites, which often referred to as the "ceramization" process.
Oxidation Resistance
During the surface treatment steps, the Anti-Oxidation Coating is the key process to enhance the oxidation resistance of the material in high temperature environments.

We manufacture the carbon matrix applications (carbon-carbon and carbon-ceramic) started from carbon fibers.
How to make C/C composite?
Carbon fiber performs
We use 2.5D or 3D carbon fiber performs.
Densification
Multi cycles of carbonization (Densification) to reach needed density and mechanical properties of the composite.
High-Temperature Graphitization
Heated to temperatures between 2000°C and 3000°C, which converts the carbon matrix into a more ordered graphite structure.
Anti-Oxidation Coating
The surface of the carbon-carbon composite should be coated with protective layers to improve oxidation resistance and durability in extreme environments.
Carbon fiber performs
We use 2.5D or 3D carbon fiber performs.
Densification to C/C material
Multi cycles of carbonization (Densification) to reach needed density and mechanical properties of the composite.
Ceramization to carbon-ceramic material
As the molten silicon infiltrates the carbon fiber preform, it reacts with the carbon to form silicon carbide (SiC) ceramic phases.
Post-Processing
Heat treatment may be applied to improve the microstructure. Machining is done using diamond tools due to the hardness of SiC.
