Strain birefringence of Kevlar aramid fibers
Journal of Applied Polymer Science, 1987AbstractWe have measured the strain birefringence of Kevlar aramid fibers under static loading via a spectrophotometric method. At very low strain rates, the birefringence of Kevlar fibers increases markedly with increasing strain. On initial straining, the birefringence increases even at relatively constant modulus.

Creep and strength retention of aramid fibers
Journal of Applied Polymer Science, 2012AbstractCreep tests at ambient conditions have been carried out on Kevlar 49 and Technora yarns covering a wide stress spectrum (10–70% average breaking load) for a long period of time (up to a year). The results confirm that Kevlar 49 and Technora yarns show a nonlinear behavior at stresses below 40% of the breaking load and a linear behavior at ...

Structural Properties of Aramid Fibers and Their Influence on Fiber Adhesion
1990Aramid fibers exhibit low adhesive behaviors that are believed to result from fiber morphology, however, the morphology-property relations are not well understood. In this report we compare Kevlar-49 and Technora aramid fibers to evaluate the relations between adhesive behavior of aramid fibers and their morphology. Ion implantation of Kevlar-49 fibers

Kevlar and Other Aramid Fibers
2018The name poly-paraphenylene terephthalamide, doesn’t exactly roll of the tongue, which is presumably why Dupont gave it the much cooler commercial name of Kevlar. Kevlar was invented by Stephanie Louise Kwolek (1923–2014) and Paul Wintrop Morgan (1911–1992) at E. I. du Pont de Nemours and Company for which US patent 3287323A “Process for the production

A new coupling agent for aramid fibers
Journal of Applied Polymer Science, 1989AbstractVarious compounds were used for the surface treatment of aramid fibers in order to promote adhesion to polymeric matrices. The improvement of adhesive bond could be based either on the roughness of fiber surface or on chemical modification introduced by grafting.

AN ECOLOGICAL APPROACH FOR THE SURFACE MODIFICATION OF ARAMID FIBERS
2016Since aramid fibers have very high crystallization degree and high chemical inertness, the surface modification is needed to enhance the adhesion between fibers and matrix for the usage of composite applications. In the present study, para-aramid fibers were treated by atmospheric pressure plasma under various plasma powers to improve interfacial ...
