7. Conclusion

Around the world today, the main phenomena that have led to carbon fibers gradually gaining a foothold in the reinforcement of buildings and engineering structures are ..:

• the rehabilitation or upgrading of existing structures, either for reasons of loss of their original properties, or for reasons of compliance with new standards;

• the construction of new, lighter and more efficient buildings and engineering structures.

In the case of rehabilitation, the process of introducing carbon fiber composites has been accelerated by the development of technically reliable and competitive methods compared with the old steel-based reinforcement processes [40][41][42]...
