Physical and Mechanical Properties of Laminated Beams of Durian Wood (Durio Zibethinus .murr) and Artocarpus with the Addition of Bamboo Rope (Gigantochloa Apus)

Introduction

Laminated beams have become a popular solution for utilizing small diameter wood into strong structural materials. This innovative approach has gained attention in the construction industry due to its potential to reduce waste and create sustainable building materials. The use of laminated beams made from durian wood (Durio Zibethinus .murr) and artocarpus (Artocarpus odoatissimus) with the addition of bamboo rope (Gigantochloa apus) is a novel approach that has not been extensively studied. This study aims to investigate the physical and mechanical properties of laminated beams with the addition of bamboo rope, with a focus on analyzing the effect of bamboo on the strength and resistance of the beams.

Background

Laminated beams are composed of multiple layers of wood, which are bonded together using adhesives. The addition of bamboo rope to laminated beams is a relatively new concept that has shown promise in improving the physical and mechanical properties of the beams. Bamboo is a highly renewable and sustainable material that has been used in various applications, including construction and engineering. The addition of bamboo rope to laminated beams can potentially enhance the strength, stiffness, and durability of the beams.

Methodology

This study employed a combination of experimental and analytical methods to investigate the physical and mechanical properties of laminated beams with the addition of bamboo rope. The following tests were conducted:

*** Density: This test measures the material density per unit volume, which provides a picture of the weight and strength of the beam. *** Water Content: This test demonstrates the percentage of water content in the material, which affects the strength and resistance to weather changes. *** MOE (Modulus of Elasticity): This test measures the stiffness of the beam in holding elastic deformation when given a burden. *** MOR (Modulus of Rupture): This test shows the strength of the beam in holding the burden before experiencing a broken. *** IB (Sticky Determination): This test measures the strength of the adhesive between the laminated layers. *** Delamination Test of Hot and Cold Water: This test assesses the ability of the beam to withstand the separation of layers due to changes in extreme temperature.

Results

The results of the tests showed that laminated beams with the addition of bamboo have an average value of:

Density: 0.46
Water content: 13.89%
MOE: 45035 kgf/cm²
MOR: 301 kgf/cm²
IB: 21.75 kgf/cm²
Hot water delamination/cold: 40.55% and 39.46%

Discussion

Statistical analysis with a 95% confidence interval showed that the addition of bamboo does not have a significant effect on MOR, IB, and delamination tests. However, the arrangement of laminated beams with the addition of bamboo turned out to have a significant impact on density, water content, and MOE. This indicates that bamboo rope can increase the stiffness and density of laminate beams, without sacrificing its bending power.

Conclusion

This study provides concrete evidence that the use of rope bamboo can be an innovative solution to improve the quality and durability of laminated beams. The results of this study open new opportunities in the development of environmentally friendly construction materials by combining the strength of wood and bamboo flexibility. In the future, further research can be done to optimize the composition and arrangement of laminated beams with bamboo rope. This can include adjusting the ratio of bamboo use, the type of adhesive used, and testing of more diverse environmental conditions.

Future Research Directions

Further research can be conducted to optimize the composition and arrangement of laminated beams with bamboo rope. Some potential areas of research include:

Adjusting the ratio of bamboo use to optimize the physical and mechanical properties of the beams.
Investigating the effect of different types of adhesives on the strength and durability of laminated beams.
Testing the performance of laminated beams with bamboo rope in various environmental conditions, such as high temperatures, humidity, and exposure to chemicals.

Implications

The results of this study have significant implications for the construction industry, particularly in the development of sustainable and environmentally friendly building materials. The use of laminated beams with bamboo rope can potentially reduce the environmental impact of construction projects, while also improving the quality and durability of the buildings.
