Análisis computacional de un ensayo de flexión por 3 puntos de un material sándwich natural compuesto de fibra de ichu y núcleo de corcho aglomerado

Abstract

Today, environmentally sustainable technologies are obtaining great implications in various industries. In this
paper, natural composite materials are proposed as an alternative to the use of synthetic composite materials
used in aerospace, structural, shipbuilding, automotive applications, etc. [1]. This alternative is a subject of
interest to researchers, as can be seen in recent research about natural composite materials such as A. [2] and
ichu fiber [3],[4], which have mechanical properties that are comparable and even superior to those of fiberglass.
Based on those investigations, the objective of this present paper is to propose a sandwich material composed
of ichu fiber laminates and a cork core, combining in this sense their properties, in order to obtain a highly
resistant natural compound to the bending stresses. The results will show the stress field according to the Von
Mises criterion, the deformation field and the máximum stress field, where it can be observed that, according to
the computational analysis developed, the sandwich material presents a structural behavior dependent on the
orientation of the fibers in laminated layers.
