Nanotubes absent in tire tread wear

A tyre with a tread enhanced with single wall carbon nanotubes underwent accelerated wear and handling simulation tests conducted by Akron Rubber Development Laboratory. The tests aimed to evaluate the performance of the tyre under various conditions.

During the tests, the tyre was subjected to rigorous wear and handling simulations to mimic real-world usage. These simulations included high-speed driving, cornering, and braking, which put significant stress on the tyre's tread.

After the tests, the tyre was carefully examined to analyze the presence of carbon nanotubes. Luxembourg-based OCSiAl, a leading producer of carbon nanotubes, conducted an analysis of the captured airborne particles. The analysis revealed that there were no free-standing nanotubes found in the particles.

This finding is significant as it indicates that the carbon nanotubes integrated into the tyre's tread did not become airborne during the accelerated wear and handling simulations. This is crucial for ensuring the safety of both the users and the environment.

The results of this study provide valuable insights into the performance and durability of tyres enhanced with carbon nanotubes. By demonstrating that the nanotubes remain securely embedded in the tread, it paves the way for further advancements in tyre technology.
