Although carbon fiber is used to repair and strengthen concrete structures for a short time, it has developed rapidly. The main reason is that carbon fiber sheet reinforcement has many advantages:
1. The construction is simple and rapid, no template, fixture, support, etc. are needed;
2. Without increasing the structural weight, the weight of the carbon fiber sheet is 200g/m2～300g/m2, the design thickness is 0.111mm～0.167mm, and the weight of epoxy resin is also very light, which has negligible influence on the weight of the structure;
3. It can adapt to the reinforcement of various structural shapes;
4. It can be pasted in multiple layers. It can be overlapped and pasted in one part according to design requirements.
