Micromechanical modeling of MXene-polymer composites
Polymer composites are considered among the most promising materials for functional and structural applications. Improvement of mechanical properties of polymer composites using nanomaterials has generated much interest in recent years. This study aimed to predict the tensile strength and determine the damage mechanism of MXene-polyvinyl alcohol and MXene-epoxy composites. All parameters such as particle size, mechanical properties and interface layer strength were calibrated by finite element modeling with respect to experimental results. The influence of aspect ratio, volume fraction and MXene flake alignment on final mechanical properties of representative volume element models were inve…
Novel hybrid polymer composites with graphene and MXene nano-reinforcements: computational analysis
This paper presents a computational analysis on the mechanical and damage behavior of novel hybrid polymer composites with graphene and MXene nano-reinforcements targeted for flexible electronics and advanced high-strength structural applications with additional functions, such as real-time monitoring of structural integrity. Geometrical models of three-dimensional representative volume elements of various configurations were generated, and a computational model based on the micromechanical finite element method was developed and solved using an explicit dynamic solver. The influence of the geometrical orientation, aspect ratio, and volume fractions of the inclusions, as well as the interfa…
