“…Honeycomb sandwich has shown a remarkable impression on mechanical performance by bringing high the stiffness/weight and strength/weight ratios, which are supported by complicated structure for weight reduction. The target productions were implemented for several applications such as the automotive, naval, and transportation industries (Zinno et al, 2011;Huang et al, 2012;Crupi et al, 2013;Partridge & Choi, 2017). The mechanical performance could be varied based on the structure due to varied size, thickness, and shape, but the main contribution was on an array of hollow cells built between thin vertical walls.…”

The honeycomb sandwich structure has been extensively investigated for its mechanical performance. Modification in improving such mechanical properties is an innovation required for honeycomb sandwiches, especially by adding a random fibers reinforcement inside a sheet panel plate. This study was developed random fiber reinforcement using natural fiber of Oil Palm, Sugar Cane, and Coconut, which constructed by the commercial software code of MATLAB. This investigation analyzed the performance of three-point bending behavior using the finite-element model, which provides four levels of fiber condition to observed: 0, 50, 100, and 150 fiber numbers. Ansys Workbench/Dynamic code was chosen to predict mechanical performance such as stress and displacement analysis. In the fiber development study, a series of numerical simulations were carried out with two types of fiber orientation reinforcement, unidirectional and chopped randomly. The hybrid orientation was also implemented in this research by combining unidirectional and chopped fiber, which was fixed at 150 numbers and then varied in three sets: S50/C100, S100:C50, and S75/C75. As a result, it was confirmed that the fiber reinforcement enhances the stiffness of the structure, which contributed a lot to the promotion of the bending resistance capacity and energy absorption. Especially, unidirectional fiber orientation has shown a significant increase in absorbing stress during testing. The fiber reinforcement sandwich demonstrated better mechanical behavior in the simulation, as reported by the hybrid system, and this was influenced by the unidirectional orientation.
