Development of a Fuzzy Model for Prediction of Elastomer Properties

Abstract

Elastomers are amorphous polymers widely used in many applications. Degradability and durability of elastomers are very important properties, which can be strongly influenced by several types of physical and chemical processes such as impact of weather conditions, aging etc. These processes can cause structural changes, which may lead to the destruction of the quality of elastomer materials, like a deterioration of their mechanical and electrical properties, and ultimately a total loss of material functionality. A large number of investigations with various experimental procedures were carried out in order to provide a better understanding of the relationship between the structure of material and its mechanical properties. This paper presents a Fuzzy model, which was constructed for anticipation of elastomers behavior based on experimental research data. In addition, a linear model was made, based on the measured and literature data, for assessing the effect of radiation and deformation on properties of elastomer specimens. The Normalized Roth Mean Square Error (NRMSE) and the Roth Mean Square Error (RMSE) were used to evaluate the results of the Fuzzy model.
