An Adaptive Neuro‐Fuzzy Inference System for Modeling Mechanical Properties of Tapioca Starch‐Poly(Lactic Acid) Nanocomposite Foams

Abstract

Abstract Tapioca starch, poly(lactic acid) and Cloisite 30B nanocomposites foams, with clay contents of 1, 3, 5 and 7% (w/w), were prepared by a melt‐intercalation method. Multiple inputs single output models were developed to predict radial expansion ratio, unit density, bulk compressibility and spring index of the nanocomposite foams. An individual ANFIS model was developed for each mechanical property using clay content, temperature, pressure and torque as input parameters. All models preformed well with R 2 values > 0.71. All models had very low root mean squared error values.
