Abstract: Glass fiber reinforced composites are widely used due to their low cost and good mechanical properties. Conductive glass fiber reinforced composites will further expand the application field of them, and be important direction of future development. This paper reviews the types, structures and properties of conductive glass fibers at home and abroad, and analyzes the effects of different conductive glass fibers on the properties of functional glass fiber composites. Finally, the development trend of polymer-based conductive glass fiber functional composites is discussed based on the current applications and limitations of conductive glass fiber and its composites.
