Figure 3 shows XRD patterns of Kevlar fiber before and after surface modification. The three diffractograms have the same peaks at 2θ =20.9º , 23º , and 28.6º which correspond to (hkl) planes...

Jan 14, 2019 · Here, we report on structure–property correlations of two new classes of commercial DuPont Kevlar fibers, termed “K29 sample test” and “K49 sample test,” as well as conventional K29 and K49 fibers.

Jan 24, 2019 · In this work, we aim to explore new aspects of the skin-core morphology of Kevlar® 29 fibers and specify their mechanical properties. To achieve this, we used a focused electron beam to reach the...

The X-ray diffraction (XRD) result also evidenced the formation of LIG. The XRD pattern of Kevlar showed intense peaks centered at 20.5°, 22.8°, and 28.6°, corresponding to (110), (200), and (004) diffractions , respectively.

It has been found that the XRD I A /I B ratio is highest for CNF grown on NiP-coated heated Kevlar by flame deposition in Figure 5 (d). It is because of the extra carbonaceous materials or...

This study deals with the effect of particle size and its distribution on the rheological behaviour of STFs and ensuing impact resistance of Kevlar® fabrics treated with them.

Jan 30, 2019 · The X-ray diffraction (XRD) patterns of the KNA, PEG, and KNA/PEG composites are shown in Figure 3c. The sharp and intense peaks occurring at around 19.27 and 23.32° in the XRD pattern were diffraction peaks of PEG because of its regular crystallization.

Feb 1, 2001 · On-line studies of structure and morphology changes in Kevlar 49 fibers during stretching were carried out using synchrotron simultaneous small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD) techniques.

Jan 5, 2021 · In this work, the ANF is firstly hydrolyzed in NaOH aqueous solution to realize carboxylation. Subsequently, the carboxylated ANF is covalently crosslinked by bio-inspired polydopamine (PDA) and assembled to be a paper-like film through vacuum filtration.

Kevlar® has a unique combination of high strength, high modulus, toughness and thermal stability. It was developed for demanding industrial and advanced-technology applications. Currently, many types of Kevlar® are produced to meet a broad range of end uses.
