The reinforcing fiber is a kind of fiber that is refined through processes such as impurity removal, slag removal and surface treatment. It is made by melting selected basalt, diabase and other materials as the main raw materials in a high-temperature furnace at 1400 °C and then centrifugally spinning them into a fibrous shape.
