Effect of CNT Morphology and Alignment on the Interfacial and the Elastic Properties of Nanocomposites

Alian A.R., Meguid S.A., University of Toronto, CA

Carbon nanotubes (CNTs) are typically curved, agglomerated and aggregated as a result of van der Waal interactions and electrostatic forces. It has been proven experimentally that CNT morphology and alignment affect the mechanical, electrical, and [...]

The Coupled Electro-Mechanical Behaviour of Nanocomposites

Wernik J.M., Meguid S.A., University of Toronto, CA

In the past two decades, practical realisation of composites began to shift from microscale-reinforced composites to nano-reinforced composites using carbon nanotubes (CNTs). There are a number of advantages that result from dispersing CNTs into polymeric [...]

Multifunctional Nanocomposites: Modeling and Characterization

Wernik J.M., Meguid S.A., University of Toronto, CA

Unlike traditional adhesive bonds, where only one material property is enhanced, multifunctional systems are capable of fulfilling several design requirements (e.g., strength/toughness, sensing, actuation, and condition monitoring). In this research, we intend to introduce this [...]

Interfacial Shear Strengths of Carbon Nanotube Reinforced Polymer Composites

Wernik J.M., Ornwell-Mott B.J.C., Meguid S.A., University of Toronto, CA

This paper expands on the existing literature of CNT polymer interfaces and describes the development of a multiscale computational model used to investigate the interfacial properties of nonbonded CNT polymer systems. Specifically, in this work, [...]

Atomistic-Based Continuum Modeling of the Interfacial Properties of Structural Adhesive Bonds

Wernik J.M., Meguid S.A., Ruda H., University of Toronto, CA

This work is concerned with the multiscale modeling of nano-reinforced structural adhesive bonds (SABs) that are typically used in the transport industry, with the aerospace sector being the prime target. Specifically, it is our objective [...]

Modeling and Simulation of Multi-walled Carbon Nanotubes using Molecular Dynamics Simulation

Wong C.H., Liew K.M., He X.Q., Tan M.J., Meguid S.A., Nanyang Technological University, SG

Molecular dynamics simulation is performed on the buckling behavior of single and multi-walled carbon nanotubes under axial compression. Brenners second generation empirical potential is used to describe the many-body short range interatomic interactions for single-walled [...]

Design and Development of Nano-reinforced Bonds and Interfaces

Sun Y., Meguid S.A., Liew K.M., Ong L.S., University of Toronto, CA

This investigation focuses on the design and development of nano-reinforced adhesively-bonded high performance joints. The influence of homogeneous dispersion of carbon nanotubes and alumina nanoparticles on the cohesive strength, interfacial properties and mechanical behaviour of [...]
