FRP rock bolt is made of glass fiber reinforced polymer, is a new emerging composite material product that replaces metal anchor rods. Using glass fiber as the reinforcing material and polyester resin as the base material, it is pulled by a dedicated pultrusion machine and solidified into a fully threaded glass fiber reinforced plastic rod body through a preform mold at high temperature and pressure. Add resin cartridge, dome plate, and nut to form a fiberglass anchor rod.
Mainly used for tunnel support, surrounding rock surface anchoring, slope anchoring, coal mine roadway and semi coal rock roadway support, as well as various underground engineering support and deep foundation pit anchoring.
Specifications & Techical Data
Characteristics
lighter weight than steel
The rod body is light (only 1/4 of the weight of the same volume of steel), easy to install and construct, and can be operated by a universal anchor bolt machine, reducing labor intensity and saving transportation costs;
2. Non corrosive, strong environmental resistance, no reflection of electromagnetic waves, can meet the needs of permanent support;
3. Easy to cut without generating sparks, convenient for fully mechanized mining operations, conducive to production safety and improving production efficiency;
4. higher strength than steel;
5. non-magnetic, low electic conductivity
5. The rod body is fully threaded, with strong gripping force and strong anchoring force;
6. According to the support requirements, the length of the cut anchor rod can be adjusted arbitrarily.
