| چکیده مقاله |
| The fuel cell must be under the appropriate contact pressure, which is done by using two thick steel end plates that are very heavy. Therefore the use of a newly developed endplate with light weight is necessary. One suitable alternative is honeycomb sandwich structure. In this study, the honeycomb sandwich panel with aluminum honeycomb core and epoxy glass composite faces has been analyzed under three-point bending test with the aim of replacing it with fuel steel end plate. To analyze the flexural behavior, the finite element method is used by Abaqus software. The thickness of honeycomb cell foil is investigated as an effective parameter on flexural strength and the effect of this parameter on the flexural behavior of the sandwich panel is analyzed. Also, critical bending force, flexural strength,flexural modulus and force-displacement diagrams are obtained. In the end, the results of numerical analysis of sandwich panels are compared with each other. |
