| Abstract | ||||
| The influence of both electron beam irradiation and step-crosslinking process on the high abrasion furnace (HAF) carbon black loaded natural rubber (NR) vulcanizates are reported. With irradiation, a higher crosslinking density, ν, thermal conductivity, λ, glass transition temperature, Tg, and decreased specific heat capacity, Cp, have been observed for the irradiated materials as compared with the unirradiated ones. Meanwhile, the step-crosslinking process has a slight effect on the crosslinking density, glass transition temperature and thermal properties of these composites. The results of such changes in thermal conductivity are explained with the help of a simple modified model. | ||||
