Expert Commentary
Known as the Apparent Horizontal Shear Strength of Pultruded Reinforced Plastic Rods (Short-Beam Method). This is the D2344 equivalent for round rods. Because the rod is curved, standard flat supports would crush the fibers. MTO provides V-Notch support rollers that match the rod’s radius. This ensures the 3-point bend load induces interlaminar shear rather than compressive crushing, providing a valid measure of the resin-to-fiber bond in fiberglass utility poles and structural rods.
