Design and Manufacturing Bio Composite (Sugarcane Bagasse – Polyvinyl Acetate) Panel that Characterized Thermal Conductivity

Abstract

The use of sugarcane bagasse for providing avaibility of raw material have been attracting attention. The benefits using natural fiber such as sugarcane bagasse are eco-friendly, low cost considerations because widespread avaibility, high stiffness, better thermal stability, and biodegradability. Sugarcane bagasse and (Polyvinyl acetate, PVAc) have been shown to possess the ability of being applied as raw material for manufacturing of bio composite panel at 10mm thickness (fixed variable) by three mesh sizes (20,30 dan 40) with ratio of the composition 95:5, 90:10 and 85:15%. The specimen have been emphasized at 3:2 and 2:1. This research was conducted to investigate possibility of manufacturing bio composite panel that its characteristic resistance to the thermal conductivity. This bio composite speciments were tested for thermal conductivity test according to ASTM E-1225. The results revealed that optimum design for bio composite panel obtained that emphasis at 3:2, filtered by mesh size 20, ratio composition sugarcane bagasse 85% and PVAc 15%. The test result shown that panel has thermal conductivity resistance value (R) 17,089 °C/W. Thus, it can be concluded that bio composite panel can be manufactured successfully from sugarcane bagasse and PVAc as the matrix mixture.

FEM simulation of bending and torsion tests of similar size RHS but of the different production options

“…The latter requires an account of the physical conditions of the test deformation, the complexity of the geometric shapes of the section and the material properties of the specimens to be as accurate as possible, which presents certain difficulties [4][5][6][18][19][20][21][22]. Studies of the complex characteristics of strength and stiffness are performed for sections of different shapes (open and closed) [23], of different materials (including non-metal) [24,25], non-welded and welded [19,24,26,27], taking into account the complexity of E3S Web of Conferences 234, 00079 (2021) https://doi.org/10.1051/e3sconf/202123400079 ICIES 2020 the shape of the final product, location and load in real construction [23,26,27]. This defines the deflection values as the characteristics of sections stiffness, and magnitudes of stresses as characteristics of sections strength.…”
