1.What is FRP Anchor Bolt?

Glass reinforced plastic (FRP), also known as GFRP, is used in coal mine support. That is, fiber reinforced plastics generally refer to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics with glass fiber or its products as reinforced materials are called glass fiber reinforced plastics, or glass steel.

2.FRP Anchor Bolt application fields:

• Coal mine rock lane
• Construction and Building Trades
• Coal mine support    

3.Advance of FRP Anchor Bolt:

 High strength glass fiber pultruded bolt (basalt fiber bolt) is a composite material with unsaturated resin as the basic material and glass fiber as the         reinforcement material. The synthetic resin has good chemical properties and high characteristics of glass fiber, which determines the performance   advantages of glass fiber reinforced plastic composite material that cannot be matched with other materials.

• Light weight, high strength, easy to cut, no spark in use, to ensure the safety of coal mine production
• Thread can be used on any part of any strip, extremely high embedding strength, strong corrosion resistance
• It can not only ensure the safety of underground coal mines, but also solve the support function of coal mine anchors, which can greatly improve the efficiency of coal mining, reduce the damage of coal cutting machine teeth, and reduce production costs.

Because FRP is a kind of composite material, its performance can be adapted to a very wide range, so its market development prospects are very broad.
