Pultruded Fiber Reinforced Polymers (FRPs) are a class of novel composite materials with remarkable strength (comparable or even greater to that of steel) and resistance to environmental effects. However, the strongly orthotropic behavior of these materials and the relatively high deformability and spatial variability in mechanical properties bring challenges to the widespread adoption of these elements in structural applications. To this end, the orientation and distribution of the fibers are the most influential parameters that affect both the ultimate strength and stiffness of the specimens. This work presents an experimental campaign conducted on GFRP specimens in uniaxial tension and 3-point bending; coupon specimens with three different fibers orientations (namely 0, 45, and 90 degrees) were tested to characterize the ultimate strength and failure modes Results of such experimental campaign are first presented, and detailed statistical measures of the so-obtained strength values are presented with the ultimate goal of characterizing the variability in mechanical properties in commercially available profiles.
