Abstract:

Closed-cell aluminum foam is the type of foam where its pores, or "cells," are closed, forming a pocket of air or a bubble. Closed-cell aluminum foam is used in different fields, such as aerospace, structural, railway, shipbuilding, and many others. This is due to its lightweight, sound and vibration absorption properties, excellent heat insulation, non-combustibility, environmental friendliness, mechanical damping, and many other beneficial properties [1]. A closed-cell aluminum foam contains air pockets or bubbles, which makes it challenging to build its 3D and 2D geometric models for further studies like Finite Element Analysis and other non-destructive experimentation, i.e., numerical modelling [2],[3]. This study focuses on the numerical and geometric modelling of the closed-cell aluminum foam. There has been a rising need for more research on how to model the closed-cell aluminum foam so that it can be studied and expanded in its application [3]. Several studies have shown how to model closed-cell aluminum foam using different modelling techniques, such as cell structure and shape [4], [5]. This study aims to conduct a parametric modelling of the closed-cell aluminum foam using the CT (Computed Tomography) images of the foam to reconstruct 3D models using Materialise Mimics V26 software and Matics V18(its twin). The reconstruction will be conducted by varying different parameters, like segmentation and other mesh-processing parameters, to develop models. The geometric properties of these models will be compared to the actual measured geometric properties to determine which set of parameters gives the accurate model. Also, to determine how the reconstruction steps affect the geometry of the models.
