Research progress of basalt fiber and fabrics

In order to better grasp the properties and application fields of basalt fiber,this papermakes a systematic summary on previous stud ies.It introduces its main chem ical compositions and the development process,with focuses on the characteristics and applications.Basalt fiber is characterized by high tensile strength,high modulus,chem ical resistance,and broad working temperature range.It is natural,environmentally friendly,and non-toxic material.Basalt fiber can be widely applied in such materials as composite,insulation and friction.Based on the analysis of early research,it puts forward the idea to further expand its application and pred icts that as the 21st century new fiber,basalt fiberwill play an important role in many fields.
