On the morphology of aromatic polyamide fibers (Kevlar, Kevlar-49, and PRD-49)
Journal of Macromolecular Science, Part B, 1983Abstract Three types of aromatic polyamide fibers (Kevlar, Kevlar-49, and PRD-49) were studied by transmission electron microscopy, secondary electron imaging, and electron diffraction techniques. Ultramicrotomy, ion-thinning, and brittle fracture techniques were used to prepare specimens which revealed both longitudinal and transverse fiber structures.

Fear of litigation is like a horror film. After a disturbed graduate student threatened to burn down the home of a faculty member in my department, we called a mentor at the student’s prior university and asked why no related information was passed on to us. She said the student threatened to sue them if they said anything negative to anyone.

Kevlar fibres were hydrolyzed in a concentrated aqueous solution of either sulphuric acid or sodium hydroxide. The hydrolyzed fibres were characterized by measuring the tensile strength and the interlaminar shear strength (ILSS). The active sites on the hydrolyzed surface were determined by the dyeing-decolorizing method.
