Bending Strength of Apus Bamboo Fiber Reinforced Asphalt Composite Materials as Small Ship

Abstract

Bamboo is generally widely used as a material or construction material in homes. However, the use of bamboo as a raw material for shipbuilding is not yet available. To make bamboo as a material in shipbuilding, the bamboo is assembled or made into a composite to meet class standards as a material for shipbuilding. In this study, the composites used were apus bamboo fiber and asphalt. The method of making the composite uses the hand lay-up method with variations of 1 layer of reinforcement, 3 layers of reinforcement, and 5 layers of reinforcement. The dimensions of the test specimen size refer to ASTM D 790-3 which is then carried out by bending tests to determine the strength of the material due to loading and the elasticity of the material. Furthermore, the results of the bending test will be analyzed using the Anova method and compared with the standard material class in ship construction. Results Asphalt composite material with apus bamboo fiber has the highest bending test value of 27,068 Mpa and the lowest bending test value of 25,998 Mpa. Based on these results, it is stated that the Bamboo reinforced asphalt (BRA) material has not been able to match and even exceed the Bamboo reinforced plastic (BRP) material in the woven, non-woven and random fiber variants. It is influenced by the diameter, and the strength of the shape between the fiber and the matrix.

The Flexural Strength and Impact Toughness of Bamboo Reinforced Latex-Asphalt Composite

“…Based on the data presented in Table 7, the flexural strength value of apus bamboo-reinforced latex-asphalt is 6.382 MPa, the flexural strength value of apus bambooreinforced asphalt is 27.018 MPa [27], the bamboo reinforced plastic variant has a flexural strength value of 160.80 MPa [13], and Lloyd's Register sets a minimum flexural strength value of 80 MPa [28]. Latex-asphalt reinforced with apus bamboo is far below the flexural strength value of apus bamboo-reinforced asphalt (which is a variant of 3 layers of apus bamboo fiber reinforcement without latex addition) with a difference of 20.636 MPa.…”
