Advantage and Application of FRP Rock Bolt


FRP rock bolt is made of glass fiber reinforced plastic special unsaturated polyester resin as the basic material, glass fiber reinforced plastic fiber as the reinforcing material, by special pultrusion machine traction, through the prefomed mold under high temperature and high pressure solidification into full thread glass fiber reinforced plastic rod body, plus resin anchoring agent, tray and nut to form FRP rock bolt.

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.

  • High strength: the tensile strength of the rod body is ≥300MPa;
  • High tensile strength: torque≥40N·m;
  • Light weight, about 1/4 of the metal bolt of the same specification;
  • Can cut, not easy to damage the cutting machine;
  • The surface is antistatic, flame retardant, and does not produce sparks when cutting;
  • Corrosion resistance, heat insulation, long-lasting durability, and good bonding force with resin anchoring agent.
