Abstract

Since many years ago bamboo has been used, in addition to wood, for structural components in rural areas due to easily growth and its short harvest time. The properties of laminated bamboo depend on many aspects, among others: quality of glue, lateral stresses during manufacture and roughness of bamboo lamina. This research used Bambusa Dendrocalamus Asper (local name: Bambu Petung) and aimed to determine the effect of artificial dented surface of the laminas on mechanical properties with variable lateral stresses. The dimensions and the types of the specimen were based on ISO 2004 standard. The age of bamboo specimens was 6 years and the lateral stresses were varied from 0 MPa to 2.5 MPa with 0.5 MPa interval. Physical properties of the specimen such as water content (humidity), specific gravity, were performed prior to the mechanical tests (tensile, compression, shear and flexural tests). Analysis of results was performed by statistical method, in addition to scanning electron microscopy for further inspection of microscopic deterioration.
