Results of Mechanical Tests of Composite Material Used in Strengthening Reinforced Concrete Structureswith External Reinforcement

The results of the composite material (FRP laminate) tensile tests are presented. The main mechanical characteristics of the FRP (tensile strength, relative elongation, modulus of elasticity along the fibers, Poisson’s ratio) were determined for specimens 20 mm wide (according to GOST 25.601) and 50 mm (the most useful FRP laminate’s width in real strengthening practice). Diagrams of deformation and loading are obtained. During the tests, it was established that the tensile strength of FRP laminates depends on the relative area of destruction.
