Carbon fiber reinforced engineering
Carbon fiber reinforcement method The use of reinforced carbon fiber coated on the outside of the damaged structure, strengthen the fiber with special epoxy resin fixed to the structure, the strengthening of fiber and structural body into one, to increase the structure of the grip strength and toughness ( Such as the column of the axial force, beam bending moment and shear) to resist external forces. Only in the coating before strengthening the fiber should be the original structure of the flaws repair (such as cracks or steel exposed, etc.).

● Carbon fiber material with light, high strength, corrosion resistance, aging resistance, durability, physical stability and many other advantages.
● Repairing reinforced concrete structure with carbon fiber material is close to the concrete structure, and the tensile strength of the carbon fiber material is used to enhance the bearing capacity of the component.
● This technology has the advantages of simple and quick construction, safe and reliable, good durability, can adapt to a variety of complex structure shape, the appearance of the original structure and many other advantages.

Features
● High tensile strength, is the same section of steel 7-10 times.
● Light weight, the proportion of ordinary steel only 1/4.
● Good durability, resistance to chemical corrosion and harsh environments, the destruction of climate change.
● Construction is convenient and quick, saving effort, the construction quality is easy to guarantee.
● Wide range of applications, concrete components, steel structure, wood structure can be reinforced.
● Can greatly improve the carrying capacity of components, seismic performance and durability.

Use
● All kinds of buildings of the beam, pillars, concrete version of the reinforcement.
● Reinforced concrete structures, bridges and buildings of the beam, column, panel reinforcement.
● Reinforcement of tunnels, harbor facilities, chimneys, warehouses and factories.

Reinforced Carbon Fiber Reinforcement Method
1. Strengthen the carbon fiber reinforcement method The use of reinforced fibers coated on the outside of the structure, strengthen the fiber to epoxy resin fixed in the structure, the strengthening of fiber and structural body into one, to increase the strength and toughness of the structure (such as column The axial force and beam bending moment and shear).

2. The construction steps are as follows:

  (1)Advanced surface treatment:
  The concrete surface loose part of all the removal, all cracks must be low-speed low-pressure method to perfusion and then EPOXY mortar (SP502 mixed with light sand 1: 1.5) stirring to adjust to paste.
  (2)Coating EPOXY Primer SP-PN:
  The EPOXY primer was evenly coated with a brush on the applied surface, with a 1M² of about 0.2 kg.
  (3)Coating EPOXY Base resin:
  After the primer is completely dry (about 4 to 6 hours after priming), EPOXY base resin is applied to the applied surface.
  (4)Attached to strengthen the fiber:
  In the EPOXY base resin is not premixed before the strengthening of the fiber will be attached to the surface of the reinforcement position, and hand direction in the direction of fiber, so that the reinforcing fiber smooth attached to the reinforced wall.
  (5)Coating EPOXY Base resin:
  After the strengthening of the fiber, the EPOXY base resin was applied to the surface of the reinforcing fiber, so that the resin was coated with the resin.
  (6)Paste a layer of carbon fiber cloth, the amount of base grease consumption of about 0.7kg, two about 1.7kg.
  (7)Surface finish after completion: according to the owner or architect specified surface layer to complete the surface.
※ (8)The speed of hardening is controlled by the atmospheric temperature, absolutely can not increase or reduce the amount of hardener mixture to control the hardening speed, change A agent and B mixture ratio will cause hardening, reduce the physical properties of the glue.
  (9)If you accidentally touch the hands or skin, please use a toluene cloth to wipe, and then wash with soap and water.
