- High tensile/flexural strength
- Precision machining of C/C
Typical Engagement Scope
- Vacuum Furnace Hardware
- High-Temperature Load-Bearing Fixtures
Execution Focus
- Fiber orientation
- Density achievement
Program Evaluation Matrix
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Density | 1.4 - 1.7 g/cm³ | Balances strength and porosity. |
| Fiber Architecture | 2D or 3D C/C composite by load direction | Fiber orientation controls strength, thread retention, and long-term deformation. |
| Operating Atmosphere | Vacuum or inert gas; oxidation protection if required | C/C composite strength is excellent at temperature, but oxygen exposure must be managed. |
| Load Case | Static load, fixture spacing, and thermal-cycle count | Tray sag, bolt shear, and creep risk depend on the real support condition. |
Program Selection Logic
| Decision Factor | Selection Logic | Buyer Check |
|---|---|---|
| Load at temperature | Choose C/C composite when graphite is too brittle or molybdenum adds too much thermal mass. | Provide load, support spacing, furnace temperature, and cycle count. |
| Fiber architecture | 2D C/C can fit plates and trays; 3D architecture is preferred for multi-directional stress and threads. | Clarify bending direction, thread engagement, and any fastener preload. |
| Oxidation boundary | C/C composite is strongest in vacuum or inert environments; oxygen exposure needs protection. | Share atmosphere, leak risk, cleaning practice, and cooldown handling. |
Production, Inspection, and Export Flow
| Stage | Production / QC Checkpoint | Buyer Evidence |
|---|---|---|
| 1. Load-case review | Define temperature, support spacing, fastener preload, tray load, and cycle count. | Application sketch, fixture drawing, load estimate, and atmosphere notes. |
| 2. Fiber architecture | Choose 2D or 3D C/C blank according to bending, shear, and thread loads. | Material route with density and architecture recommendation. |
| 3. Densification and machining | Process C/C blank, then machine threads, holes, plates, and tray geometry. | Dimensional report for load-bearing and assembly-critical features. |
| 4. Strength-risk check | Review delamination, thread stripping, sag, and edge damage before shipping. | Visual inspection plus agreed mechanical evidence if required. |
| 5. Handling and packing | Prevent abrasion and impact on lightweight C/C fixtures during export. | Packing photos and handling notes for furnace maintenance teams. |
Risk and Mitigation
- Delamination: Using 3D needle-punching or specialized lay-up techniques.

Buyer FAQ
How long does C/C fabrication take?
The densification process is lengthy; custom C/C blanks take 2-4 months.
When is C/C composite a better choice than graphite?
Choose C/C composite when the part carries load, sees repeated thermal shock, needs threaded strength, or fails because graphite is too brittle.
What information is needed for C/C tray or fastener design?
Provide load, support spacing, maximum temperature, atmosphere, cycle count, thread standard, and the current failure mode if replacing another material.
Can C/C composite be used in oxidizing atmospheres?
C/C composite performs best in vacuum or inert gas. If oxygen exposure is expected, the application needs oxidation-risk review and possible protective treatment.
