CNTs reinforced metal composites has great potential due to their superior properties, such as light weight, high strength, low thermal expansion and high thermal conductivity. The current strengthening mechanisms of CNT/metal composite mainly rely on CNTs' interaction with dislocations and CNT's intrinsic high strength. Here we demonstrated that laser shock loading the CNT/metal composite resu...

An aluminum matrix composite with dispersed carbon nanotubes (CNTs) was produced via flake powder metallurgy using a micro-rolling process and vacuum hot pressing (VHP), followed by conventional rolling macro-rolling process. The microstructure mechanical properties of the composites were studied. In addition, new quantitative model introduced to study dislocation density based on microstructur...

Combining conductive micro and nanofillers is a newway to improve electrical conductivity. Micrometric silver flakes and nanometric carbon nanotubes (CNTs) exhibit high electrical conductivity. A new type of hybrid conductive adhesives filled with silver flakes and carbon nanotubes (DWCNTs or MWCNTs) were investigated. High electrical conductivity is measured as well as improved mechanical prop...

The rapid progress in developing MgB2 superconductors since its relatively recent discovery has made this material a strong competitor to other lowand high-temperature superconductor (HTS) materials for technological applications, especially in niche markets such as magnetic resonance imaging (MRI). Thanks to the lack of weak links and the two-gap superconductivity of MgB2, [2,3] a number of di...

Optimizing the interactions between matrix and reinforcement components is key to attaining high-performance composite materials. Yet, balancing reinforcing–matrix phase for synthetic composites remains a great challenge. Here, combined methodology using molecular atomic layer deposition (M/ALD) demonstrated tailoring carbon nanotube (CNT) interfacial interactions, yielding high-performance-rei...
