FRP -rebar

  FRP rebar   is a composite material made of high-strength glass fiber as a reinforcing material, synthetic resin as a matrix material, and an appropriate amount of auxiliary agents. It is called glass fiber reinforced plastic (English abbreviation FRP).  Commonly used   fiberglass rebar   in the market is diameter from Φ3mm～Φ36mm. Glass fiber: also known as alkali-resistant glass fiber, alkali-resistant fiberglass roving is the rib material of glass fiber reinforced (cement) concrete (GRC). It is 100% inorganic fiber. It is ideal alternative to steel and asbestos in non-load-bearing cement components. Alkali-resistant glass fiber is characterized by good alkali resistance, can effectively resist the erosion of high-alkali substances in cement, strong binding force, elastic modulus, impact resistance, tensile strength, high bending strength, and temperature resistance. Strong humidity change ability, excellent crack resistance and impermeability perfo...

  FRP rebar  used as a reinforcement cage material, is a rod material made of longitudinally continuous glass fiber and a thermosetting polymer resin through a pultrusion process and surface treatment. The polymer surface is spirally wound by glass fiber bundles and wrapped with resin to form steel-like teeth to improve the bonding performance with concrete. Compared with ordinary steel bars, it has light weight, high tensile strength, high static shearing force but low dynamic shearing force, strong corrosion resistance, low elastic modulus, and cannot be processed on site (such as welding , bending) and other characteristics.   The connection of main rebar under force should be connected by a steel U-shaped card, and the U-shaped card should fit the diameter of the bar. The number of U-shaped cards at the connecting end of each bar shall not be less than two. Other positions connection between GFRP rebar and steel rebar,  GFRP rebar  and GFRP rebar c...
