Graphene/epoxy interleaves for delamination toughening and monitoring of crack damage in carbon fibre/epoxy composite laminates
Xusheng Du,Helezi Zhou,Helezi Zhou,Weifu Sun,Hong-Yuan Liu,Guangnan Zhou,Huamin Zhou,Huamin Zhou,Yiu-Wing Mai +8 more
TL;DR: In this article, the incorporation of 1.0% of graphene into epoxy was found to significantly improve the matrix fracture energy by ∼150% and reduce the thermal expansion coefficient by ∼30%.
Journal ArticleDOI
Effect of defects on thermal conductivity of graphene/epoxy nanocomposites
TL;DR: In this paper, the effect of four common types of defects on the interfacial thermal transport between the epoxy and graphene was systematically investigated by using molecular dynamic simulations and the underlying mechanism was explicated by using the phonon vibration power spectrum.
Journal ArticleDOI
Delamination toughening of carbon fiber/epoxy laminates by hierarchical carbon nanotube-short carbon fiber interleaves
TL;DR: In this article, hierarchical short carbon fibers (SCFs) synthesized with carbon nanotubes (CNTs) were used as CNT-SCF interleaves to increase the mode I delamination fracture energy G IC of carbon fiber/epoxy (CF/EP) composite laminates.
Journal ArticleDOI
On adhesive properties of nano-silica/epoxy bonded single-lap joints
TL;DR: In this article, the effects of nano-silica on the adhesive properties of epoxy were systematically studied by single lap-shear tests under quasi-static and cyclic loadings.
Journal ArticleDOI

TL;DR: In this article, a general silane-assisted processing that maintains an effective control of the chemistry, architecture and functionality of these porous structures is presented. And the introduction of silane bonding tailors both the porous microstructure and the surface property of the lightweight aerogel effectively, subsequently providing improved mechanical properties and versatile functionalities.
