“…Many studies have reported the benefits of adding graphene and its derivatives in the PE matrix to reinforce the thermal, electrical, and mechanical properties of the PE matrix. However, several reports have been reported on the preparation method of PE/graphene nanocomposites [ 10 , 11 , 12 , 13 , 14 ], the improvement in the interfacial interaction between PE-functionalized GNPs [ 15 , 16 , 17 , 18 , 19 ], the dispersion and alignment of graphene in the composite samples [ 20 , 21 ], and the construction of the hybrid network structures of graphene with other conductive fillers [ 10 , 22 , 23 ]. Although the GNPs size is an important factor, only a few works have studied the GNP’s size effect on the mechanical properties of High-Density Polyethylene (HDPE) nanocomposites [ 24 , 25 , 26 ].…”

A series of high-density polyethylene nanocomposites filled with different diameter sizes (5, 15, and 25 μm) of graphene nanoplatelets at various amounts (0.5–5 wt.%) are prepared by the melt-mixing method. The effect of diameter size and filler content on the mechanical properties is reported, and the results are discussed in terms of morphology and the state of dispersion within the polymer matrix. The measured stiffness and strength of the nanocomposites were found to be mainly influenced by the filler aspect ratio and the filler-matrix adhesion. Fractography was utilized to study the embrittleness of the nanocomposites, and the observations revealed that a ductile to brittle transition is caused by a micro-deformation mechanism change in the nanocomposites. Several micromechanical models for the prediction of mechanical properties of nanocomposites, taking into consideration filler aspect ratio, percolation effect, and interphase regions, are considered. The three-phase model proposed by Ji accurately predicts the stiffness of graphene nanoplatelets with a higher diameter size, while Takayanagi modified model II was found to show good agreement with the experimental results of smaller ones at low filler content. This study demonstrates that the diameter size of the filler plays a central role in determining the mechanical properties.

“…The finite element-based approach was proven to be a very valuable tool for studying the mechanical and damage behavior of various composite materials. In the field of finite element-based analysis on nanocomposites, the majority of published works are focused on graphene for improving the mechanical characteristics of nanocomposites [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ]. Recently, the finite element-based methods gained attention in studying the damage behavior of various composites.…”

View full text Add to dashboard Cite

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 interface properties between the nano-reinforcements and the matrix on the mechanical behavior, was determined. The results of the presented research give initial insights about the mechanical and damage behavior of the proposed composites and provide insight for future design iterations of similar multifunctional materials.
