Estudio experimental de la influencia de microesferas de vidrio en la respuesta mecánica a flexión de estructuras panal reforzadas con espumas sintéticas

Abstract

This thesis studies the bending behaviour of honeycomb structures by varying their weight through the introduction of glass microspheres. For this purpose, four different types of synthetic foam specimens were manufactured, varying the percentage by volume of glass microspheres between 20%, 30% and 40%. Afterwards, three point bending tests were performed on each of these groups of specimens based on ASTM D7264/D7264M-15, thus obtaining data that allowed us to determine the variation of the resistance of the material by plotting the standardized results and comparing them with pure material without glass microspheres. As a contribution, we present data of the behavior of this material under impact gravity test, maintaining the same composition of the bending tests. The standard ASTM-D3763-18 is applied for this purpuse and we will present the results of the experiment together with its respective analysis.
