Table 2: Results of tensile testing of FRP specimens.

The plates were subjected to static tension, and the properties were determined on solid specimens without a concentrator. Mechanical characteristics of the samples: E 11 = E 22 = E 33 = 24,6 GPa; ν 12 = ν 13 = ν 23 =0,128; G 12 = G 13 = G 23 =2,9 GPa.
