This article presents a methodology to model curved CNTs and Graphene nanoplatelets for generating nanocomposite volume elements. The focus is placed on comparing the effect of curvature on isolated reinforcements and on cubic VEs where the interparticle distance is of interest, such as in the case of detecting percolation. The results support the idea that curvature reduces the 3D span of both reinforcements in the same way, whereas percolation appears affected only in the case of CNTs. However, for GNPs the difficulties in generating Volume Elements with a sufficiently high volume fraction could support only preliminary considerations.

Abstract
This article presents a methodology to model curved CNTs and Graphene nanoplatelets for generating nanocomposite volume elements. The focus is placed on comparing the effect of curvature on isolated reinforcements and on cubic VEs where the interparticle distance is of interest, such as in the case of detecting percolation. The results support the idea that curvature reduces the 3D span of both reinforcements in the same way, whereas percolation appears affected only in the case of CNTs. However, for GNPs the difficulties in generating Volume Elements with a sufficiently high volume fraction could support only preliminary considerations.Pubblicazioni consigliate
