GFRP (Glass Fiber Reinforced Polymer) rock bolts are specialized structural elements used in geotechnical and mining applications to reinforce and stabilize rock masses. They are made of high-strength glass fibers embedded in a polymer resin matrix, typically epoxy or vinyl ester.

One of the significant advantages of GFRP rock bolts is their excellent corrosion resistance. Unlike traditional steel bolts, which are susceptible to corrosion when exposed to moisture, chemicals, or harsh environments, GFRP rock bolts are non-metallic and do not rust. This property ensures long-term durability and reduces the need for maintenance or replacement.

GFRP rock bolts can be installed using various techniques, depending on the specific application and geological conditions. Common installation methods include resin anchoring, grouting, or mechanical anchoring. Proper installation ensures effective load transfer from the rock mass to the bolt.
