High-Strength Carbon Nanotube Film from Improving Alignment and Densification.
TL;DR: A new method involves the continuous production of a hollow cylindrical CNT assembly and its condensation on a winding drum and the alignment and densification of CNTs in the film are improved by controlling the winding rate and imposition of mechanical rolling, respectively.

Improvement of interfacial adhesion and nondestructive damage evaluation for plasma-treated PBO and Kevlar fibers/epoxy composites using micromechanical techniques and surface wettability.
TL;DR: Based on the propagation of microfibril failure toward the core region, the number of AE events for plasma-treated PBO and Kevlar fibers increased significantly compared to the untreated case and the results of nondestructive AE were consistent with microfailure modes.

Relationship between structure and mechanical properties for aramid fibres
TL;DR: It has been found that the rate of shift of the Raman bands per unit strain is proportional to the fibre modulus except for fibres with large differences in molecular orientation between fibre skin and core regions, which reflects the higher orientation of the skin.
