Fiberglass Rock Bolt Introduction
FRP rockbolts, also known as fiber-reinforced polymer (FRP) rock bolts or glass fibre reinforced polymer (GFRP) rock bolts, are a type of support system used in underground mining, tunnelling, and civil engineering projects to reinforce and stabilize rock formations.
Products Description
what is fiberglass rock bolt?
FRP rockbolts are made of a composite material consisting of continuous glass fibers or other high-strength glass fibers embedded in a polymer resin matrix, typically a thermoset resin like polyester, vinyl ester, or epoxy.
Due to the good chemical properties of the special resin and the high-strength of the glass fiber, coupled with the special manufacturing process, which determined that the FRP rock bolt has the incomparable performance advantages of other materials.
