    Abstract The behavior of Parallel Strand Lumber (PSL) subjected to impact loading was studied. Eighteen 100 mm ×100 mm×650 mm flexural specimens were tested under both static and impact loading conditions. It was found that the failure modes of PSL were similar under both loading conditions with the specimens failing mostly by a combination of shear and flexural modes. PSL also exhibited stress rate sentitive characteristics; however, the rate sensitivity was affected by the localized damage at the contact surface.

    Résumé Le comportement de composites unidirectionnels à base de bois (PSL) soumis à des tests d'impact a été étudié. Dix-huit éprouvettes de 100×100×650 mm ont été testées en mode statique et en mode impact. Le mode de rupture observé pour chaque type d'essais était similaire: une combinaison d'effets de cisaillement et de flexion. La sensibilité du composite unidirectionnel PSL au taux de déformation a également été vérifiée. Toutefois, cet effet tend à s'amenuiser en raison de l'endommagement localisé aux surfaces de contact.
