The objective of this work was to develop a microscale model allowing to describe the growth of gas bubbles during the foaming of a rubber matrix in injection moulding conditions. The description of the foaming at the level of the bubble is based on a model first proposed by Amon and Denson [1]. The model describes the growth of numerous cells...

The objective of this work is to develop a numerical model allowing to predict the foaming process of a rubber matrix in injection molding conditions. This is achieved in two parts. The first one is a microscale model that describes the growth of a bubble, based on Amon and Denson's work [1], according to whom the foam is divided into identical...

The objective of this work is to model the chemical foaming of an industrial EPDM rubber compound formulation. The chemical foaming is caused by OBSH chemical decomposition with nitrogen formation. The vulcanisation system is sulphur based. Both reactions are controlled by the thermal history.Two approaches have been compared to model the...

The objective of this work is to model the chemical foaming of an industrial rubber compound formulation in controlled thermal history. The chemical foaming is caused by a chemical agent (CA) decomposition with nitrogen formation. The vulcanisation system is sulphur based. Both reactions are controlled by the thermal history.The objective is to...
