Abstract
In this paper the results of a quantitative description of polyurethane
nanocomposites with boehmite microstructure are reported. These
nanocomposites have higher abrasive wear and thermal resistance. Quantitative
image analysis of SEM images has been performed in order to describe the
microstructure of the polyurethane and its nanocomposites. The dependence
between the sizes of the spherulities obtained on brittle fractures of materials and
their resistance properties were analysed.
Keywords: nanocomposites, polyurethane, boehmite, lactic acid, image
analysis.
1 Introduction
Machine components made from polyurethane are mainly used in mining [1–4].
Often, they can also have high resistance for abrasive wear and thermal stability
[2, 3]. Components like nano-clays or plate-shaped, for example kaolin, mica
and aluminium hydroxides, have been added to the polymeric matrix to obtain
required heat resistance, high modulus and some other physical and mechanical
properties [5–8]. However, the macroscopic properties of such composites
heavily depend on the dispersion of the added particles in the polymer matrix
[7, 8]. In order to improve this dispersion, modified nanofillers are used and
special processing routes are employed [8].
This paper presents the application of quantitative image analysis to the
description of morphological properties of boehmite modified using lactic acid
and its nanocomposites. Fracture surface images of nanocomposites were
