FRP threaded rods are made of FRP special unsaturated polyester resin as the base material and FRP fiber as the reinforcing material. Due to the good chemical properties of the special resin and the high strength of the glass fiber, coupled with the special production process, it is determined that FRP threaded rods have performance advantages that other materials cannot match.

Advantages of FRP threaded rods:
High strength: the tensile strength of the rod body is greater than or equal to 300MPa; the torque is greater than or equal to 40N m, the tensile strength is light, and it is about 1/5 of the metal anchor rod of the same specification; it can be cut, and it is not easy to damage the cutting machine. The surface is antistatic, flame retardant, cutting No sparks, corrosion resistance, thermal insulation, durable, good bonding force with resin anchoring agent.
Disadvantages of FRP threaded rods:
At present, the shortcomings of mining FRP threaded rods are mainly manifested in: 1. The formula of the rod body material needs to be improved to improve the performance of the bolt and reduce the cost of the product; 2. The production process and installation process, especially the embossing of the bolt need to be improved. Improvement: In terms of production technology, many domestic manufacturers are working hard to improve, and FRP threaded rods as a new type of mining support material must be a trend.
