Team Cracks 100 Year-Old Rubber Mystery
Scientists at the University of South Florida have cracked a century‑old mystery about reinforced rubber, showing that carbon black particles create a Poisson’s ratio mismatch that dramatically stiffens the material. The breakthrough follows 1,500 molecular‑dynamics simulations equivalent to about 15 years of compute time and unifies competing theories of particle networks, glue‑like interactions, and space‑filling effects. The new mechanistic insight gives tire engineers a scientific foundation to design longer‑lasting, higher‑traction, and more fuel‑efficient tires. It also promises safer rubber components across aerospace, power, and industrial sectors.
