Fiber-reinforced composite rebar is a kind of composite material made of polymer resin as the matrix and glass fiber, basalt fiber or carbon fiber as the reinforcement. GFRP. It has excellent properties such as high strength, light weight, corrosion resistance, insulation, heat insulation, and wave transmission.

1. Production process Glass fiber reinforced ribs (GFRP) are compounded of high-performance resin materials (UPR, VER, EP, PU) and high-strength fibers through a pultrusion process. Yarn threading, resin impregnation, mold preforming, heat curing, traction and pultrusion, surface treatment, cutting/packaging

2. Application areas: subway ground connection walls, retaining piles, coastal projects, roads, bridge projects, rail transit projects (tramways), tunnel projects, coal mine tunnel support (side roof anchoring), foundation pit support, Slope support.

3. Compared with steel bars 1) High strength: the tensile strength is 2-3 times that of steel bars of the same specification. 2) Cost saving: The material cost is slightly lower than that of steel bars, and it is factory prefabricated, so there is no need for on-site secondary processing. 3) Save construction time: There is no need to manually break the wall of the cave door. The shield machine directly digs and breaks it. There is no damage to the shield head, which can shorten the construction time. 4) Light weight: easy to construct and operate. 5) Corrosion resistance: No rust problems.
