US Patent 7939156 Composite concrete/bamboo structure

Composite concrete/bamboo structural members and process of manufacture therefor. The bamboo material includes layers formed of bamboo segments which have been dried and glue coated. The segments are substantially free of outer nodes and husk and inner membrane material prior to application of glue. The longitudinal axes of the segments in each layer are generally parallel to one another and are arranged in a mold to surround the surface of a cured concrete core. The layers of segments are heated, compressed and bonded together until the glue cures around the concrete core into a single integral structure. The concrete core is preferably reinforced with steel REBAR rods.
