Abstract

Biodegradables material nowadays selected as a solution for replace the current material in packaging industry. Kenaf fibre is a good material for substitution of chemical material according to their properties. Comparison between Simulation of MATLAB Simulink and cushion of Kenaf fibre by analyzed their dynamic shock properties and dynamic cushion curves are the focus of this project. Generally, this project is using Stress Energy method to evaluate the capability of a Kenaf fibre cushion to withstand the sudden shock resulting fiom free fall. The result will be guide by the simulation of Matlab Simulink software. A series of cushion test for 50 samples was carried out to determine the peak acceleration, (G's) for simulation and Kenaf fibre cushion at difference drop height, thickness and mass. There are 5 mass type used to generate the Static loading. These static loading choose by Dynamic energy calculation in Stress energy method. There are 3 type thickness of Kenaf fibre cushion used in this project. The result of peak acceleration, (G's) from both methods used to develop the Dynamic stress versus Dynamic energy graph. This graph generates Stress energy equation and regression percent. The equation also give the value of (a) and (b) used in generate the cushion curve. The regression value R2 will indicate of how well the equations fit the data and; R2 simulation 81.2% and experiment 92%. Generally, the shape of curves for experiment same shape as simulation but difference at minimum peak acceleration and static loading. Kenaf fibre cushion with thickness 25 mm at drop height 406 mm give peak acceleration 121.7 G compare to simulation 170.6 G, while for sample thickness 50 mm peak acceleration 62.0 G and simulation 83.6 G. Thickness 75 mm gives the lowest peak accelerations where for Kenaf fibre 40.7 G and simulation 59.6 G. Comparing the minimum peak acceleration will give the conclusion that there is decreasing of G peak when thickness increases. The result can conclude that kenaf fibre cushion with 25 mm thickness suitable for handheld part, 50 mm suitable for durable part and 75 mm suitable for stable part according to table of fragility levels.
