Title Statement Development of glue-laminated bamboo and bamboo-wood combination for structural uses Physical Description 67-87 Summary, Etc. The technical viability of producing glue-laminated bamboo and bamboo-wood combination at various layers for structural purposes using modified commercially available glue was studied. Two bamboo species, namely; kauayan tinik (Bambusa blumeana S.A & J.H. Schultes) and botong [Dendrocalamus asper (Schultes f.) Baker ex Heyne] and one timber species, yemane (Gmelina arborea Roxb.), were used as raw materials. Urea formaldehyde (UF) + ammonium chloride (NH4Cl) and UF + NH4Cl + isocyanate were used as glue. The effects of species, glue type and type of laminates (bamboo-bamboo or bamboo-wood) were evaluated based on dry and wet shear tests. Strength properties in bending, compression parallel to the grain and shear along glue line of laminated bamboo and composite bamboo-wood lamination were also determined. These were found comparable with the strength properties of traditional timber species used for general purposes, e.g. for beams, girders, flooring, etc. Using the FPRDI system of strength classification, laminated bamboo falls under Class 2 (moderately high strength), the same group where such commercial timber species as kamagong (Diospyros discolor Willd.), molave (Vitex parviflora Juss) and narra (Pterocarpus indicus Willd. forma indicus) belong. The bambo-wood lamination falls under Class 3 (medium strength), the group to which Philippine Mahogany Species such as white lauan (Shorea contorta Vidal), red lauan (Shorea negrosensis Foxw.) bagtikan [Parashorea malaanonan (Blanco) Merr.] and tangile [Shorea polysperma (Blanco) Merr.] belong Subject Added Entry - Topical Term Strength properties   Glue shear   Bamboo laminates   Bamboo-wood laminates           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
