Abstract: The present invention resides in one aspect in a building material that comprises wood and a composite polymeric material that is combined with the wood in a heterogenous admixture. The composite polymeric material incorporates fibers in a polymeric matrix. The fibers can be chopped, continuous, or combinations thereof. In addition, the fibers can be unidirectionally oriented and/or randomly oriented. Suitable fibers for use in the composite polymeric material are glass, polymers, carbon, combinations thereof, and the like. However, the present invention is not limited in this regard as other fibers known to those skilled in the pertinent art to which the invention pertains can be used without departing from the broader aspects of the present invention. Suitable polymeric material for the polymeric matrix include thermoplastic polymers, thermosetting polymers, or a combination of thermosetting and thermoplastic polymers.

Abstract: A method for manufacturing a reinforced beam having a bonded tensile reinforcement member includes assembling a tensile reinforcement member to a beam, wherein adhesive is disposed between the tensile reinforcement member and the beam. A load is applied to the tensile reinforcement member to define a pre-tensioned tensile reinforcement member. A force is applied to urge the beam and the pre-tensioned tensile reinforcement member together. The load is released on the pre-tensioned tensile reinforcement member prior to the adhesive becoming cured, allowing longitudinal ends of the tensile reinforcement member to slide relative to the beam at longitudinal ends of the beam, and thereby forming a reinforced beam having a bonded tensile reinforcement member.

The bladder wall and the outer layer define an elongated annular space with the fabric positioned therein. Tension is applied longitudinally to the fabric and fluid is introduced into the cavity to at least partially inflate the mold and shape the fabric. The mold is shaped to a desired shape while maintaining the fabric under tension. The elongated annular space and the fabric are infused with a rigidification material. The rigidification material is hardened while maintaining the fabric in tension to form a rigid hollow composite construction member.
