The Analysis of Size and Arrangement Effects of Petung Bamboo Split Fiber to the Matrix Interface Bond with Laminated Bamboo Split Fiber as Construction Materials for Wooden Vessels

Abstract

Bamboo is an extraordinary natural material. Bamboo can grow quickly, is cheap and widely available. The material property is light but harder and stronger than wood or glass fiber composites. The purpose of this study was to determine the effect ofarrangement and size of petung bamboo split fiber to the matrix interface bond of laminated bamboo split fiber. The benefits of this study can contribute knowledge and innovation to the development of science in the field of vessel material technology in education field, especially in the field of shipping. This research was carried out by compressive test, tensile test, and shear test to the matrix interface bond of laminated bamboo and petung bamboosplit fiber with the tangential and radial test directions (x, y, and z axis) using the ASTM D143 standard.After testing, it can be concluded that the tensile strength and compressive strength of the brick arrangement is better, while for the shear strength, it is better in the parallel arrangement, furthermore the thicker the bamboo split size, the greater the stress value. The average results obtained for tensile test is 44 kg/cm2 , the shear test is 38,5 kg/cm2 , and the compressive test is 341,05 kg/cm2 . The average compressive strength of these results can be classified into Strong Class III on BKI (Indonesian Classification Bureau) of Wooden Ships. The direction of the best tensile strength test is on the Y axis, the direction of the best shear strength test is on the Z axis, and the direction of the best compressive strength is on the X axis. The higher the glue Interface value for each cm2 , the greater the interface bond strength due to the need of glue in mm/cm2 is higher, on the contrary the lower the glue Interface value in each cm2 , the lower the interface bond strength due to the need of glue in mm/cm2 is lower.

Mechanical Properties Evaluation of Laminated Composites of Petung Bamboo (Dendrocalamus asper) and Coconut Coir Fiber as Ship Construction Components

“…It can be used on ships' ivory, leather, decks, masts, deck boards, girders, and above-water construction. Another study also found that the thinner the thickness of the bamboo lamina applied for ship structures, the greater the value of the interfacial/ bond strength [10]. Another study discussed imp- [10].…”
