Abstract

AbstractThe present study focuses on exploring the relationship between various properties of tire tread composites and filler system using machine learning. Four different types of machine learning algorithms, such as multiple linear regression (MLR), artificial neural network (ANN), support vector machine regression (SVR), and classification and regression tree, are used for predicting 0 °C tanδ, 60 °C tanδ, tensile strength, and Shore A hardness of natural rubber nanocomposites from carbon nanotubes dosage, silica dosage, and total filler equivalent. The results showed that the introduction of interaction terms and square terms into the inputs evidently improved the prediction capability of MLR, ANN and SVR, and MLR possessed the smallest prediction errors (<5%). The established MLR models are further used to design tire tread composites with high 0 °C tanδ, low 60 °C tanδ, and appropriate Shore A hardness and tensile strength. The predicted values are in good agreement with the experimental results, indicating that the established MLR models can be used for properties prediction and design of tire tread composites effectively. Moreover, k‐fold cross‐validation is proved to be a reliable technique to evaluate the predictive capability of the MLR models.
