Analysis of E-Glass Particle Reinforced PLA Matrix Composite for 3D Printing Applications using ANSYS

Abstract

In this work, the E-glass in the powder form is considered as reinforcement with PolyLacticAcid (PLA) to analyze a composite using the micromechanics approach. The particle reinforced composite properties were estimated through Finite Element software ANSYS. Finite element model was validated with analytical expressions. For evaluating the proposed composite for 3D printing applications, a plate was modeled. This composite plate was analyzed under combined thermal, mechanical loading. Studies were carried out to predict the normal and shear stresses generated in the composite plate. The E glass powder volume fraction was increased from 5% to 30%. The results of normal and shear stresses were compared with pure PLA matrix. It was found that E-glass reinforced composite was superior when compared to pure PLA. The results of the present work suggest addition of E-Glass particles in pure PLA matrix when used as a filament to improve the properties of 3D printed component.
