FRP (Fibre Reinforced Polymer) composites are materials that can be used to create external reinforcement (plating) systems for existing masonry or reinforced concrete structures. They consist of an organic matrix reinforced with a fibre fabric. In cases requiring connections, the system is completed with braided connectors for connection to the structural element to be reinforced.
FRP composites are used where high mechanical performance is required without burdening the structure. The application method makes interventions quicker and less invasive than with traditional systems, reducing processing time and also the possible interruption of building activities.
| Components of on-site systems | Required: reinforcement fabric (carbon or glass fibre) and epoxy impregnating resin Optional: epoxy pre-treatment, epoxy regularising filler, braided connectors |
| Components of preformed systems | Required: carbon plate, epoxy bonding resin Optional: epoxy pre-treatment, braided connectors |
| Application thickness | Negligible (< 5 mm) |
| Substrate | Concrete or masonry |
| Examples of use | Increase in flexural and shear strength of beams Increase in load-bearing capacity and ductility of pillars by confinement Increase in the load-bearing capacity of masonry-concrete floors Consolidation of vaulted structures and arches Exterior ringing of masonry structures Reinforcement of structures with a wide radius of curvature |
