© 2019 Elsevier Ltd In recent years the embedded element (EE) technique, which is based on the superposition of meshes, has been introduced into finite element (FE) modelling of composite materials. When compared to conventional approaches employing a single continuous mesh this technique has a number of advantages, among which are simplicity in th...
© 2018 Elsevier B.V. Debonding at the fiber/matrix interface is an important failure mechanism in composite materials. It controls, among others, the intralaminar cracking process. A large amount of experimental data exists indicating that the addition of carbon nanotubes (CNTs) in a composite can hinder onset and development of these cracks. Here ...
© 2018 Elsevier Ltd The success of carbon nanotubes (CNTs) in increasing toughness of polymers and their composites is often attributed to the additional energy consumed by CNT debonding and pull out. In this work we demonstrate that this mechanism alone can only lead to modest improvements in toughness and that the true toughening power of CNTs li...
In this study, we constructed hybrid three-dimensional (3D) filler networks by simply incorporating a relatively low content of one-dimensional carbon nanotubes (CNTs; 0.0005-0.25 vol %) and a certain content of two-dimensional boron nitride (BN; 30 phr) in a silicone rubber (SIR) matrix. As indicated by transmission electron microscopy observation...

The present research work was undertaken to evaluate the rutting performance of carbon nanotube (CNT)-modified asphalt binders. Additionally, intermediate-temperature performance, aging resistivity potential, and high-temperature storage stability were also evaluated. Reported literature on rutting performance of CNT-modified asphalt binders is mai...
Material loss and degradation due to erosion remains a major concern in engineering applications for composite materials. A finite element based model has been developed to predict the erosion behavior of unidirectional carbon fiber-epoxy (CFRP) composites subjected to solid particle impacts. In this model, the CFRP plate is subjected to multiple p...
Designing environmentally friendly materials from natural resources represents a great challenge in the last decade. However, the lack of fundamental knowledge in the processing of the raw materials to fabricate the composites structure is still a major challenge for potential applications. Natural fibers extracted from plants are receiving more at...
