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