Summary

Story summary

Engineers at the University of South Florida have identified the physical mechanism behind reinforced rubber.
Their study, published in the Proceedings of the National Academy of Sciences, shows that carbon black particles transform rubber, increasing its strength.
The research used 1,500 molecular simulations to show that multiple theories about rubber's behavior are interconnected.
The findings could improve manufacturing and safety in critical infrastructure.
