Researchers at the University of South Florida have identified the mechanism that allows carbon black particles to strengthen rubber. Using advanced computer simulations, the team discovered that these particles prevent rubber from thinning when stretched, forcing the material to resist volume changes and increasing overall durability. This discovery helps solve the Magic Triangle of tire design, which balances traction, durability, and fuel efficiency. By moving beyond trial and error, engineers can now design industrial rubber and tires that reduce vehicle rolling resistance and lower carbon emissions.
