Carbon Heat Sink

Semicorex Carbon Heat Sink is a high-performance thermal management component engineered for extreme environments, including aerospace braking systems. Developed using advanced carbon–carbon composite technology, this component is designed to operate reliably under the intense thermal and mechanical loads generated during aircraft braking. Its application in platforms such as the Airbus A320 highlights its capability to meet stringent aviation standards for safety, durability, and performance.

Material Technology: Carbon–Carbon Composites

•   Low density (>1.7 g/cm3)

•    High specific strength/specific mode（＞2000 MPa/(g/cm³)）

•    High temperature resistance (3000℃)

•    Excellent friction and wear performance (20% longer life than OEM parts)

Carbon–carbon composites are produced by reinforcing carbon fibers within a carbon matrix, resulting in a material that retains exceptional strength and stability even at extremely high temperatures. Unlike metals, which can soften or oxidize under repeated thermal cycling, C/C composites maintain structural integrity well beyond 3000°C in non-oxidizing environments.

This material also offers excellent thermal conductivity, allowing rapid heat dissipation during braking events. Its low density provides a significant weight advantage—an essential factor in aerospace engineering where performance and fuel efficiency are closely linked.

Role in Aircraft Braking Systems

In aircraft such as the Airbus A320, braking systems are subjected to intense frictional forces that generate extreme heat within seconds of landing. The Carbon Heat Sink plays a critical role in managing this thermal load by:

Absorbing and distributing heat generated during braking

Preventing localized overheating that could compromise system integrity

Supporting consistent braking performance across repeated cycles

Enhancing overall system safety and reliability

The ability of C/C materials to withstand rapid heating and cooling cycles without degradation makes them indispensable in aviation brake assemblies.

Structural Design and Efficiency

The heat sink features a multi-layered, ring-shaped architecture designed to maximize heat dissipation. The stacked configuration increases surface area, enabling efficient thermal exchange with surrounding air or cooling systems.

Precision-engineered slots and channels within the structure facilitate airflow and improve convective cooling, while the circular geometry ensures uniform radial heat distribution. This design minimizes thermal gradients, which is crucial for maintaining consistent mechanical performance in braking systems.
