EXPERIMENTAL DESIGN FOR BENDING STRENGTH ALUMINUM HONEYCOMB STRUCTURE
In this study, a Taguchi model was formed for the three point bending test behaviors of aluminum honeycomb composite structures. Effect of the three independent variables (cell width, cell height and adhesive) on the dependent variable (bending forces) was determined using mix design L16(4*1 2*2) orthogonal series. As a result of the experiments, bending force values were measured. As a result of Taguchi analysis according to 'better than most' solution approach, bending force value was concluded to be optimum with the use of 58.59 S/N ratio A1 B2 C1 level namely, primary 6.78 mm for cell width and secondary 30 mm for cell height and primary epoxy adhesive. Order of importance according to S/N answer table for force factor was ordered as cell width, cell height and adhesive. 95% was significant for the force values of the factor and levels selected in ANOVA results.
