The reorientation of CNTs under the applied strain is simplified as a rigid-body movement due to a much higher Young's modulus of CNTs compared with a polymer matrix and the very weak interface between CNTs and the matrix [6].
It is assumed that the very weak interface is the reason for the poor mechanical properties of the created material.
The experimental results also suggest, that whilst the initial toughness is reduced by very weak interfaces, such composites are most likely to exhibit rising toughness behaviour.
When observed in three dimensions, an additional feature, an underlying but continuous layer located right at the barnacle substratum interface, also exhibited a very weak spectral signature similar to the particle wavefront.
In agreement, the F257E mutant oligomerizes in the closed state but only in the crystal and not in solution arguing that the remaining contact interface indeed mediates only a very weak interaction.
Bioinformatic analyses of the ligand-receptor interface between Egfr and its ligands show a very weak evolutionary conservation within this region.
So they're a very weak thing.
They have a very weak society".
or a very weak chemical interaction.
This created a potent navy but a very weak army.
In 2002 France still had a very weak broadband market.
