Abstract
Basalt fibres are gaining interest in the fibre-reinforced thermoplastic industries around the world. In this work, basalt and glass short fibres reinforced polypropylene composites were produced using twin-screw extrusion and followed by injection molding. To carry out a comprehensive study on physical and mechanical properties, the composites were produced with different proportions of fibre loadings (for both fibres 5, 10, and 20 wt %). Composites were characterized and studied for tensile (at different strain rates), flexural (at different speeds), impact, dynamic mechanical analysis, density, tensile-relaxation, melt flow index test, and rheometric properties. Results indicate that tensile, flexural, dynamic mechanical analysis, and tensile-relaxation properties increased with increasing fibre proportions in the polypropylene matrix. The melt flow and rheometric behaviors of polypropylene decreased significantly with the addition of short fibres into the matrix. The overall results showed that basalt fibres can be potentially used as replacements for glass fibre to develop these thermoplastic composites.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
