Microstructure of C/SiC (carbon fiber reinforced silicon carbide)

High-strength C/SiC

High-strength C/SiC

The C/SiC of LCT GmbH was developed as part of a project for emergency braking systems for elevators with high masses and speeds at the University of Bayreuth. Depending on the phase composition, this composite can be tailored to be either high strength or high friction under extreme thermal and mechanical stress. On the left is an example of the microstructure of our high-strength C/SiC.

Modified C/SiC for friction layers

The hard and low-wear C/SiC can be seen in the right picture. Depending on how we combine the two composite types, both in terms of sequence and layer thickness, we can further optimize your desired final product. This results in many possible components for a wide variety of applications – as shown in the following material portfolio.
