Bamboo can be engineeredfor laminate boards and other sustainableconstruction material. The adhesive type is expected to affect the laminated board's quality. This study analyzedthe physical (density, moisture content, and delamination) and mechanical (bending and shear strength) properties of betung(Dendrocalamus asper) bamboo laminated boards prepared using various adhesives. The most favorableadhesive for enhancing betungbamboo laminated boardswas determined. The bamboo lamina was arranged into boards (3 layers) measuring 30 x 15 x 1.5 cm each in length, width, andthickness.The laminated board was glued using isocyanate, epoxy, and polyvinyl acetate (PVAc)adhesives using the double glue spread technique. The laminated board was tested for its physical and mechanical properties, following the JAS 234:2003 standard. Betungbamboo laminated board with isocyanate, epoxy, and PVAc adhesiveshaddensitiesranging from 0.89 g/cm3to 0.95 g/cm3, moisture contentsof 7.64%to 24.37%, delamination ranges from 0%to 100%, modulus of elasticities from 109,000to 178,000kg/cm2, modulus of rupture values range from 709 to 1,570kg/cm2, and shear strength values of 25.0to 60.0 kg/cm2. Isocyanate adhesive was found to havethe best quality in physicaltests, while epoxy adhesive achievedthe best quality in mechanical tests of laminated boards. |
