Journal ArticleDOI
Enhancement of mechanical performance of epoxy/carbon fiber laminate composites using single-walled carbon nanotubes
Behnam Ashrafi,Jingwen Guan,Vahid Mirjalili,Yunfa Zhang,Li Chun,Pascal Hubert,Benoit Simard,Christopher T. Kingston,O. L. Bourne,Andrew Johnston +9 more
TL;DR: In this article, single-walled carbon nanotubes (SWCNT) were used to develop nano-modified carbon fiber/epoxy laminates to improve dispersion and epoxy resin-nanotube interaction.
Journal ArticleDOI
Single-walled carbon nanotube–epoxy composites for structural and conductive aerospace adhesives
Michael B. Jakubinek,Behnam Ashrafi,Yunfa Zhang,Yadienka Martinez-Rubi,Christopher T. Kingston,Andrew Johnston,Benoit Simard +6 more
TL;DR: In this article, single-walled carbon nanotubes (SWCNTs) were incorporated into an unfilled aerospace-grade epoxy system, to impart electrical conductivity while maintaining structural bonding capability, as a route for development of a structural and conductive adhesive.
Journal ArticleDOI
Large-scale production of PMMA/SWCNT composites based on SWCNT modified with PMMA.
TL;DR: In this work, a two-step method consisting of in situ polymerization of polymethyl methacrylate (PMMA) in the presence of single-walled carbon nanotubes (SWCNT), followed by the redispersion of the resulting compound in dimethylformamide (DMF), was used to fabricate SWCNT modified with PMMA.
Journal ArticleDOI
Integration of Single-Walled Carbon Nanotubes into a Single Component Epoxy Resin and an Industrial Epoxy Resin System
J. W. Guan,Behnam Ashrafi,Yadienka Martinez-Rubi,Yunfa Zhang,Christopher T. Kingston,Andrew Johnston,Benoit Simard +6 more
TL;DR: In this paper, single-walled carbon nanotubes (SWCNT) are integrated into a single component epoxy resin (aerospace grade MY0510) as well as an industrialized epoxy resins system for sporting goods.
Journal ArticleDOI
A Three Dimensional Unit Cell Model for the Analysis of Thermal Residual Stresses in Polymer Composites Reinforced with Wavy Carbon Nanotubes
Yunfa Zhang,Andrew Johnston,Ali Yousefpour,Jingwen Guan,Benoit Simard,Christopher T. Kingston +5 more
TL;DR: In this article, a numerical approach to predict the thermal residual stresses in polymer nanocomposites reinforced with a periodic array of wavy carbon nanotubes was presented, and the authors established a three dimensional unit cell model to accurately account for the waviness of the nanotube.
