FRP Soild Rock bolts

Fiberglass is a kind of fiber reinforced plastic. In technical terms, fiberglass is called composite material. Fiber-reinforced plastics are made up of two parts, a matrix, which is resin or plastic, and a reinforced plastic, which in most cases is reinforced with fiber. FRP has a wide range of properties and plays an important role in economic construction.
Jiufu Glass fiber reinforced plastic bolt is made of glass fiber as reinforcement material, polyester resin as the base material, by special pultruding machine traction, through the preforming die under high temperature and high pressure curing into full thread glass fiber reinforced plastic bolt body, plus resin anchorage agent, tray and nut composition of glass fiber reinforced plastic bolt.
Model specifications (mm) bar tensile strength (kN) bar tensile strength (MPa) connecting part and thread bearing capacity (kN)
Fhj-18 φ 18 140 650 50
Fhj-20 φ 20 180 620 80
Fhf-25 φ 25/10 185 510 80
The weight of FRP bolt is light and convenient for transportation, which can reduce the investment of roadway support material in transportation and reduce the support cost in the process of coal mining. In addition, FRP bolt can penetrate into surrounding rock and rock, which does not need to occupy the roadway section, and also reduces the cost of roadway excavation. In addition, the stability of FRP bolt support is better, and the maintenance amount of roadway is less, which can reduce the maintenance cost of the project to a certain extent.
