Optimization of Honeycomb Structures for Sandwich Panels by Response Surface Methodology (RSM)

Abstract:

This research aims to design and develop honeycomb structures for sandwich structures, focusing on enhancing the strength and reducing the weight of the components compared to the prototype. The research began with creating test models using a 3D printer and tensile testing with a Tensile Testing Machine. The data obtained from the tests were analyzed using SolidWorks software to adjust the material properties to align with the experimental results. The experimental design was conducted through the Response Surface Methodology (RSM), resulting in nine test model designs. These models were fabricated using a 3D printer, and their strength was analyzed with SolidWorks and validated through tensile testing. The experimental results revealed that six models exhibited a 133.655% increase in strength and a 7.568% reduction in weight compared to the prototype.
