Study Experimental and Numerical of Cross-Laminated Bamboo with Epoxy Adhesive

Abstract

One of the most promising processed wood products today is cross-laminated timber (CLT). Another alternative to cross-laminated timber (CLT) is cross-laminated bamboo (CLB), which can address the challenges of using wood. Cross-laminated bamboo (CLB) is a floor and wall slab made from bamboo slats arranged at 90° angles. Variations in bamboo type and size were analyzed using ANSYS numerical modeling. ANSYS is a FEM software used for the simulation and analysis of engineering products and systems. The purpose of this study was to analyze the flexural strength (MOR), modulus of elasticity (MOE), and ductility of cross-laminated bamboo (CLB) as a floor and wall slab structure. This study investigated whether it could produce satisfactory results using numerical modeling. This study used a two-point method to obtain the modulus of elasticity (MOE), flexural strength (MOR), and ductility. The experimental cross-laminated bamboo (CLB) used Petung bamboo as the test specimen, measuring 1360 mm in length, 660 mm in width, and 44 mm in thickness. Epoxy/Melamine Formaldehyde (MF) glue was used as the adhesive. Numerical modeling of the CLB, with dimensions similar to those used in the experiment, involved modeling two bamboo variations: Petung bamboo and Apus bamboo. Epoxy/Melamine Formaldehyde (MF) glue was used for the numerical modeling. The test results for the cross-laminated bamboo (CLB) showed an average modulus of elasticity (MOE) of 14.56 GPa, an average flexural strength (MOR) of 17.15 MPa, and an average ductility of 5.01. The damage behavior of the CLB was characterized by cracks in the bamboo slats and peeling of the glue. Comparison of the difference between experimental and numerical values ​​of CLB Petung bamboo at the maximum load of 19.96% and the final loading of the deflection difference of 16.29%. In numerical terms, with different types of material variations, namely Petung bamboo and Apus bamboo, the deflection difference at maximum load and final load.
