High-Temperature Carbon Composites

Utilizing Carbon/Carbon (C/C) composites to solve structural challenges in high-temperature environments where traditional graphite fails due to brittleness.

Target Buyer:Engineers pushing the limits of high-temperature fixturing.

Carbon carbon composite tray for high-temperature load bearing 1

Thermal shock immunity
Longer lifespan than graphite

Common Use Cases

Heavy Load Sintering
Aerospace Processing

Implementation Focus

Load calculations
Fiber orientation (2D vs 3D)

Application Evaluation Matrix

Evaluation Metric	Typical Range	Buyer Relevance
Flexural Strength	> 120 MPa	Carries heavy loads without sagging.
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.

Application 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.

Application Delivery and QC Flow

Stage	Delivery / 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.

Buyer FAQ

Is C/C more expensive than graphite?

Initial cost is usually higher, but total cost can improve when the application benefits from longer service life and reduced maintenance.

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.
