Optimización de respuestas múltiples (DOE/MSR) de propiedades mecánicas del material híbrido de matriz epoxi reforzada con fibra sintética (carbono) y natural (Chambira)

Abstract

Due to the demand that exists today in Materials Engineering, as the days go by, it has always been sought to help improve the mechanical properties of the new design thus meeting the user's need. The specimens were designed under the methodology (DOE / MSR) (Box – Behnken) which allowed to determine the orientation of the natural fiber, synthetic fiber and the temperature. The values that were considered were -45, 0, 45 degrees and the temperature 60, 90, 120 degrees Celsius. With the help of (Box – Behnken) 15 cases with 3 replicates were determined to determine the mechanical properties. The results obtained from the three tests were tabulated and it was observed that the best combination to obtain the optimum material should be performed with orientation1 45 degrees, orientation2 35 degrees and curing temperature 60 degrees Celsius and the MSR design regression model explains up to 95.61 percent the variability of the properties, with an overall desirability value of 0.989.
