Analysis of Bamboo Species Variation Effect Against Physical and Mechanical Properties of Laminate Bamboo Slat for Fishing Boat Construction Materials

Abstract

Several studies on the mechanical properties of bamboo slats have been carried out using various types of bamboo species, including Dendro Calamus Asper sp, Gigantochloa Apus sp, Bambusa Arundinacea sp. Until now, variations and combinations of bamboo species have not been carried out, especially about physical and mechanical properties. This paper investigates the effect of variations in bamboo species on the physical and mechanical properties of laminated bamboo slats for ship construction. Each species of bamboo has advantages and disadvantages, which are expected with this combination will produce better physical and mechanical properties. The best value of shrinkage properties occurred in the variation of Bambusa Arundinacea sp with Gigantochloa Apus, namely 3.86 %. This variation also extends the highest mechanical properties: Tensile Strength: 151.9 Mpa; Flexure Strength MOR: 118.6 Mpa; MOE: 5.54 GPa. The Bambusa Arundinacea sp and Gigantochloa Apus hybrid perfectly meet the limit requirements according to the rules of BKI: 2013, Vol vii.
