Performance evaluation of basalt fibre-reinforced polymer
Basalt fibres are made from a single origin material called basalt rock. Hence, they are referred to as inorganic, eco-friendly, non-toxic with high stability and insulating property material [27, 32, 33]. Basalt rocks are available all over the world and are formed on the earth's surface by frozen lava sent by a volcanic eruption.

Basalt usually contains 45–52 % silica (SiO 2) and oxides such as iron, calcium, and magnesium, compared to the most common igneous rocks [11]. Basaltic rocks' crushing and cohesive strengths are 170–220 MPa and 32–44 MPa, respectively [12 ...
Basalt | Definition, Properties, & Facts | Britannica
basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact. It is more usual, however, for them to exhibit porphyritic structure, with larger crystals (phenocrysts) of olivine, augite ...
