Abstract

Basalt as a filler in a polymer-based composite material fulfils the demand of being natural, environment-friendly material for the production of various composite materials. The material could be used as protective layer and the abrasion should be tested in order to evaluate the properties of the material. The cavitation test enables the evaluation of the possible service in conditions that simulate the extensive erosion. The presence of basalt in the matrix improves the resistance to cavitation. The possibility to further improve the material could be obtained using the reinforcement of the matrix itself by incorporation of submicron ceramic particles into the composite. The obtained hybrid composite material with the addition of reinforcement in the matrix further improves the cavitation resistance.

Highlights

Composite materials reached a new era in the 20th century with the use of polymer matrix and the properties of the material became tuneable in terms that by a selection of components the properties could be adjusted
The hybrid composite material consisted of a basalt powder added to a matrix that was itself composed of polyester resin and alumina particles
General mineralogy of studied basaltic rock samples is very similar, as it consists of olivine, clinopyroxene, and plagioclase as essential minerals, and accessory spinel group mineral ± volcanic glass residuum

Summary

Introduction

Composite materials reached a new era in the 20th century with the use of polymer matrix and the properties of the material became tuneable in terms that by a selection of components the properties could be adjusted. The micro-composite materials where the reinforcing phase has grains of micrometer size the rule of mixing rule applies and the general properties such as density, thermal conduction can be calculated from the component properties. The growing demands for composite materials are often supplied using environmentally unfriendly materials. The demand for inventing the materials using natural sources is growing. The mineral rocks such as basalt are well known for their good mechanical and chemical resistance [3].
