Statistical point of view on polymer (Nano)composite preparation

Abstract

Samples of nanocomposites polypropylene and montmorillonite nanofiller were prepared by the compounding in KO Buss kneader at a different rotational speed, and the resulting properties of unmodified and modified polymer matrix were evaluated. In the observation of tensile strength and E module, some improvement was noticed. In order to find if these changes are statistically significant, the set of data was evaluated by basic statistical methods. It was found that that the measured improvement of mechanical properties is significant also in the statistical point of view. © 2019 Trans Tech Publications Ltd, Switzerland.
