Prediction of the optimal vulcanization of a fiber‐reinforced elastomeric isolator made of natural rubber‐ethylene propylene diene monomer blend

G. Pianese, G. Milani, F. Milani

Polymer Engineering & Science > 63 > 8 > 2421 - 2443

To seismically isolate a structure, it is possible to interpose a rubber device between the foundation and superstructure that increases the period of the superstructure, a feature that allows the structure to be “transparent” to the seismic excitation. A package of several rubber pads typically constitutes a seismic isolator; they are 10–20 mm thick vertically interspersed with either steel laminas...

M. Manzuk, A. Roshal, K. Bestuzhev, F. Milani, more

Fusion Engineering and Design > 2017 > 124 > C > 35-39

In ITER, the interruption of high DC currents is required for plasma initiation at the beginning of each operation cycle and for protection of the superconductive coils in case of quench. Particularly, the high voltage needed for breakdown and plasma initiation will be provided by Switching Network Units (SNU), while Fast Discharge Units (FDU) will provide protection of the coils by extracting the...

Parabola-Hyperbola P-H kinetic model for NR sulphur vulcanization

G. Milani, F. Milani

Polymer Testing > 2017 > 58 > C > 104-115

A Parabola-Hyperbola (P-H) kinetic model for NR sulphur vulcanization is presented. The idea originates from the fitting composite Parabola-Parabola-Hyperbola (P-P-H) function used by the authors in [1,2] to approximate experimental rheometer curves with the knowledge of a few key parameters of vulcanization, such as the scorch point, initial vulcanization rate, 90% of vulcanization, maximum point...

A novel mathematical approach to predict the vulcanization degree of high-cis polybutadiene rubber vulcanized with sulphur is presented. The model has kinetic base, it is constituted by four reactions occurring in series and parallel and takes contemporarily into consideration, within a simplified but reliable scheme, the actual reactions occurring during polybutadiene sulphur curing, namely primary...
