DOI: 10.1016/j.polymer.2017.11.064
Abstract: Abstract We adopt here a novel approach to identify the para- and meta- aramid fibers using the available free volume in them. Positron Annihilation Lifetime Spectroscopy (PALS) has been employed to characterize the free volume… read more here.

DOI: 10.1109/tdei.2023.3348082
Abstract: Meta-aramid insulating paper, comprising precipitated fibers as the matrix and chopped fibers as the reinforcing skeleton, exhibits tremendous potential as a next-generation insulating material in high-voltage systems. However, its insulating performance is hampered by severe… read more here.
