Fibrenamics' BCR project presented in Germany
Developed by Fibrenamics - the University of Minho, this project aimed to create interlaced composite bars - BCR - for subsequent application in concrete reinforcement (beams, columns, and, in network form, slabs and floors) and soil stabilization (nailing and anchoring).
Using, in its genesis, glass, basalt, carbon fibers, or a mixture of these fibers, these rods seek to solve the current flaws of steel, which was until very recently the material most resistant known by Human Beings.

Therefore, this product is 80% lighter than steel rods, which allows reducing logistic costs related to transportation, handling, and on-site application. At the same time, these bars are highly durable, which makes it possible to eliminate the costs associated with the rehabilitation of buildings, since they do not show any corrosion caused by the environment in which they are inserted. In addition, this type of material is twice as strong as steel, and because it is made of intelligent materials, it is also possible to monitor structural deformations.
During September 20-23, the BCR - Braided Composite Rods project will be on exhibition in Berlin, Germany, at the largest international transportation technology fair - InnoTrans.
