Polymer composite materials with fibrous and disperse basalt fillers

The advantage of basalt fibres in comparison to glass fibres was demonstrated. The process parameters for production of basalt fibre are reported. The manufacturing processes in processing polypropylene composites with low combustibility and poly(ethylene terephthalate) composites filled with basalt fibres in lines based on a cascade screw-disk extruder are examined. Technology for obtaining polymer coatings using composites with basalt flakes and their properties are described.
