Abstract
Inhomogeneous heating of carbon-black filled SBR (styrene-co-butadiene rubber) cylinders was mapped by NMR imaging in situ during dynamic me chanical load. The linear relationship between T-2 and temperature was used for direct imaging of temperature profiles. Experiments were per formed as a function of shear frequency between 0 and 10 Hz and of car bon black contents between 10 and 70 phr (parts per hundred rubber). F or a composite cylinder with a hard core and a soft shell an unexpecte d heat distribution was observed.
