A wood structural member of the present invention, such as a laminated wood beam, a wood I-beam, or a truss, includes multiple synthetic fiber reinforcements. In a preferred embodiment, the reinforcements include synthetic fibers that are arranged parallel to one another and aligned with the longitudinal direction of the reinforcement and, therefore, accordingly the wood structure. The fibers are maintained in position by a resin encasement. The surface of a reinforcement to which a wood segment is bonded is adapted so that the reinforcement may be bonded to the structural member with nonepoxy adhesives, such as resorcinol, commonly used in the laminated beam industry.

[ I claim:] [1.] A wood structural member having plural wood segments attached to form a unitary structure, comprising:multiple fiber reinforcements, each of which including plural strands of fibers held within a resin casing having first and second major surfaces in which certain strands of the fibers of each fiber reinforcement present at its first and second major surfaces constitute surface fibers, at least one of the fiber reinforcements being bonded by a nonepoxy adhesive to at least one of the wood segments of the wood structural member, and each of the major surfaces of the resin casing to which a wood segment is adhered by nonepoxy adhesive is a conditioned surface to provide for the nonepoxy adhesive an effective bonding interface between the fiber reinforcement and the wood segment, wherein at least one of the major surfaces to which a wood segment is adhered by nonepoxy adhesive is conditioned so that the surface fibers protrude from the resin encasement.
