Thermoelastic properties nanocomposite chloroprene of rubber with montmorilonit
Кераміка: наука і життя, 2021 The problem that arises during the operation of tires is cyclic deformation, in which there is a conversion of mechanical energy into heat. However, due to the low thermal conductivity of rubber, repeated cyclic loads of products based on them lead to heating, which is due to the phenomenon of mechanical hysteresis.
