Abstract
A high strength, high modulus fiber is applied to uncured adhesive in the glueline of a laminar wood beam as an anti-sag agent and for improved shear strength, creep resistance, and gapability. In one embodiment, discontinuous fibers are evenly applied over the adhesive at approximately 0.25 to 1.35 wt % fiber. The applied fibers 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. In another embodiment, discontinuous fibers are used as an additive to a resin matrix for reconstituted fiber products to control dimensional change. In a third embodiment, continuous fibers are used in the glueline in a pretensioned or an untensioned way to improve shear resistance, creep resistance, and strength.
