Knitted glass-fiber reinforced PET composite were tested and numerically investigated. Using specimens with different number of reinforcing layer, one can come to the conclusion that the tensile strength is increasing with the number of reinforcing layers. The tensile stress values at less face-width dumbbell specimens are at about 5% less, as the wider rectangle shape specimens. A finite element model has been created to investigate numerically the strengthening reinforced structure. The 2D finite element result shows, that the displacements correlate to test results, and the distribution of the stress values are also acceptable.
