Currently on the market in engineering structure reinforcement and reconstruction, the most popular reinforcement technique is the paste of carbon fiber cloth reinforcement, its reason is with the advantages of this kind of material itself, such as: light weight, high strength, acid and alkali, not the original architectural space, the construction is simple and almost no wet and so on. Situations in a variety of reinforcement and reconstruction, therefore, there is always a lot of carbon fiber reinforcement scheme to bid, even if the project is not suitable for strengthened with carbon fiber sheet (CFS), or some low level of carbon fiber cloth and the use of inferior adhesive is not used for bearing structure, but still there will be a lobbyist put it put the skies. In this case, it is easy to misuse or use fake products to cause safety quality accidents.

The investigation shows that in the past two or three years, such cases have emerged, and the losses caused by them are hard to estimate, so it is worth paying attention to the design, construction, supervision and owner units of the reconstruction industry. To stop the spread of the bad behavior to administrative department of the common efforts, correctly grasp the fundamental performance of this material and its use scope, conditions, key points of design and construction. When using CFRP to reinforce the concrete structure, it is necessary to choose the qualified quality carbon fiber and adhesive.

Carbon fiber cloth as reinforcing material is stuck outside, although there are a lot of advantages, but there are some difficult to control the weaknesses, the main is that processing design is difficult to assess fire, sabotage or other accident risk of this material may be produced.
