Investigation of Basalt Fiber Reinforced Polyamide Composites

Abstract

Basalt fiber reinforced polyamide composites were investigated to determine their static and dynamic mechanical properties. The composites were compounded in an extruder and were injection molded. A glass fiber reinforced composite also was investigated. Two different basalt fibers were used with silane sizing and one of them was used also without sizing. The results show that composites with silane sized basalt fibers have properties similar to glass fiber reinforced composites, while unsized basalt fibers eventuate smaller strength and higher brittleness.
