Abstract

Currently, research work modelling of interface phenomena of nanoparticle-reinforced composite materials, notably Carbon Nanotubes (CNT)-epoxy composites are investigated across the length scales. This paper describes the kinematics of nanoparticle-reinforced composite materials as a continuum media, the formulation of governing equations (fundamentals) and the statement of boundary conditions for multi-scale modelling of the material. The identification problem for the non-classical parameters of the model has been solved by experimental results and a method of conjugated gradients. The model has been validated to predict some basic mechanical properties of a polymeric matrix reinforced with nanoscale particles/fibres/tubes (including CNT) as a function of size and also dispersion of nanoparticles. The outcome of this paper is expected to have wide-ranging technical benefits with direct relevance to industry in the areas of transportation (aerospace, automotive, rail, maritime) and civil infrastructure development.
