Research progress on basalt fiber-based functionalized composites

Abstract

Basalt fiber (BF) is a kind of high-performance fiber rising rapidly in recent years. BF is typically used in the field of structure engineering because of its high strength and high modulus. The preparation of BF-based composites first requires surface modification of BF to improve the interfacial bonding between BF and the resin matrix. With the continuous deepening of the research on BF surface modification, researchers have found that special surface modification can obtain BF-based functionalized composites, and this field has received extensive attention in recent years. In this article, research work on BF-based functional composites in recent years are summarized and reviewed from the aspects of electromagnetic shielding, water treatment, catalytic function and fire insulation. Finally, this article summarizes the BF surface modification methods, and proposes the development trends and direction of BF-based functional composites.
