A high strength, high modulus fiber (30) is applied to uncured adhesive (26) in the glue line (28) of a laminar wood beam (10) as anti-sag agent and for improved shear strength and gapability. The fibers (30) are evenly applied over the adhesive (26) at approximately 0.25 to 1.35 wt. % fiber. The applied fibers (30) are chopped fibers of aramid, carbon, glass or other high strength, high modulus fiber and are applied in lengths of approximately 0.025 to 2.54 centimeters.

Une fibre très résistante et à module élevé (30) est appliquée, en tant qu'agent anti-affaissement, sur un adhésif (26) pas encore sec, dans la ligne de collage (28) d'une poutre en bois lamellaire (10) de manière à en augmenter la résistance au cisaillement. Les fibres (30) sont appliquées uniformément sur l'adhésif (26), à raison d'environ 0,25 à 1,35 % en poids de fibres. Les fibres appliquées (30) sont des fibres découpées d'aramide, de carbone, de verre ou d'autre matériau très résistant et à module élevé, et sont appliquées sur des longueurs d'environ 0,0025 à 2,54 centimètres.
