Hierarchical Composites with Carbon Nanotube Grafted Fibres
Carbon nanotubes (CNTs) are excellent candidates for a new generation of high-strength, high-stiffness materials due to their low density, high aspect ratio and intrinsically superior mechanical properties. The present study investigates the feasibility of reinforcing conventional fibre/matrix composites by grafting CNTs onto the fibre surface. The approach is to exploit the CNT performance to ...
متن کاملHierarchical self-assembly of chiral fibres from achiral particles.
We investigate, by molecular dynamics simulation, the behaviour of discotic particles in a solvent of Lennard-Jones spheres. When chromonic disc-sphere interactions are imposed on these systems, three regimes of self-assembly are observed. At moderate temperatures, numerous short threads of discs develop, but these threads remain isolated from one another. Quenching to low temperatures, alterna...
متن کاملMapping local microstructure and mechanical performance around carbon nanotube grafted silica fibres: methodologies for hierarchical composites.
The introduction of carbon nanotubes (CNTs) modifies bulk polymer properties, depending on intrinsic quality, dispersion, alignment, interfacial chemistry and mechanical properties of the nanofiller. These effects can be exploited to enhance the matrices of conventional microscale fibre-reinforced polymer composites, by using primary reinforcing fibres grafted with CNTs. This paper presents a m...
متن کاملElastic fibres.
Elastic fibres are essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils. They endow connective tissues such as blood vessels, lungs and skin with the critical properties of elasticity and resilience. The biology of elastic fibres is complex because they have multiple components, a tightly regulated developmental depositio...
متن کاملActin stress fibres.
Animal cell movement is effected through a combination of protrusive and contractile events. Non-muscle cells contain stress fibres - bundles of actomyosin that are the major mediators of cell contraction and that can be compared to the highly organised actomyosin arrays of muscle cells. Recent studies have defined regulatory mechanisms that control stress fibre formation, placing the ROCK prot...
