Toughening mechanisms in nanoparticle polymer composites (original) (raw)

Toughening Mechanisms in Composite Materials, 2015

Abstract

The success of nanotechnology in structural applications is founded on the development of models, analytical or numerical, to predict the macroscopic fracturing behavior as a function of the molecular structure of the polymer and the nanofiller. This is particularly challenging because the final process of failure is inherently a multiscale process involving several length and temporal scales and the formulation of physically based multiscale models with real predictive capability can but stand on the identification of the inherent mechanisms of damage at the nanoscale. The present work aims to review the main damage mechanisms reported in the literature for nanoparticle-reinforced polymers, to include new insights, and to discuss predictive models incorporating these mechanisms.
