Effect analysis of the direction of fiber arrangement on interfaces of laminated bamboo fiber as a construction material for wood vessel hulls

Abstract

Bamboo is a material that can grow quickly, cheap and widely available. Its material properties are lightweight but harder and stronger than wood or glass fibre composites. The purpose of this study was to determine the effect of the direction arrangement of petung bamboo blades on the interface of the laminated bamboo fibre matrix. The benefits of this research can contribute to knowledge and innovation to the development of science in the field of ship material technology in the world of education, especially in the shipping field. This research was conducted with a compressive test, tensile test, and shear test on the interface of petung bamboo laminate blade matrix with tangential or radial test direction (x, y, and z axis) using ASTM D143 standard. After testing, it can be concluded that the shear strength and compressive strength are better with perpendicular arrangement, while for tensile strength it is better paired with woven arrangement. The average results obtained for the tensile test was 41.29 kg / cm2 (4,049 MPa), the shear test was 39.98 kg / cm2 (3.92 MPa), and the compressive test was 311.24 kg / cm2 (30 For the average compressive strength of these results can be classified into Class III on BKI Wooden Ship For the best tensile test direction on the Y axis, the best shear test direction on the Z axis, and the best compressive test direction on the X axis. The greater the glue interface in each cm2, the greater the bond strength, because the level of homogeneity increases and the strength of petung bamboo is stronger than the PVAc glue used.
