Choice of the Adequate Composite Material

5 Strengthening of Reinforced and Prestressed Reinforced Concrete Structures 

In the case of reinforcements with pultruded composite materials performed directly in the processing plant, the geometry of the pultruded sheets can be chosen among those realized by the producers. In the case of pultruded composite materials, the percentage of fibers in the composite material usually does not exceed 65 %. Even if the mechanical properties of the composite materials are mainly given by the fibers, the properties of the matrix are also very important. For this reason, it is important to use resins characterized by very high mechanical properties, such as the epoxy resins.
