The paper presents an experimental analysis of the bending behavior of pine beams
(Pinus Sylvester) retrofitted with fiber reinforced plastic (FRP) and poplar planks used as external
covering. Poplar wood was chosen because of its rapid growth in planted forests, its homogeneity
and attributes for sustainable local development, and high CO2 absorption rate. Vibration tests
were also conducted in order to evaluate the stiffness in a non-destructive way and compare it
with that obtained by means of the destructive tests. Three types of reinforcement were compared,
namely: basalt fabric (FB), carbon fabric (FC) and carbon laminate (LC). In addition, some pine beams
were reinforced only with poplar planks and used as control specimens in order to evaluate the
improvement provided by the FRP. It was observed that a strong delamination preceded the final
breakage of beam. Moreover, the results indicated that stiffness is provided mainly by the poplar
plank and not by the FRP, as was expected.
