X-ray diffraction analysis was conducted to examine the crystal structures of the carbon fibers and epoxy resin matrices in the CFRP.

1999年2月22日 · X-ray diffraction (XRD) measurements were carried out with filtered Cu Kα radiation on the diffractometer XRD-7 from Seifert and FPM. The thin film diffraction geometry with the parallel beam setting and the fixed angle of incidence of the primary beam γ=5° was used in these experiments.

A This report describes the wide-angle x-ray diffraction techniques used to examine carbon and graphite fibers and the results of several fibers. A series of commercial PAN- and pitch-based carbon fibers whose tensile moduli spanned the generally available range were examined. Crystal perfection, size, orientation, and degree of graphitizati6n

2024年7月3日 · Polarized carbon fibers find applications in the realms of health, energy, environment, defence, catalysis and smart materials. For brevities sake, the focus of the current research paper is only on the structural characterization of carbon fibers using XRD.

2018年8月6日 · The image above shows a small rod made of several carbon fibers. The image below shows the x-ray diffraction pattern in which there is some evidence of symmetry.

The structural characterization of carbonized PAN fibers was carried out by analyzing X-ray diffraction (XRD) patterns, obtained using a Philips XʼPert, X-ray diffractometer using CuKα radiation (Wavelength = 1.54056 Å) at 40 kV and 30 mA.

2019年5月6日 · A technique for studying the carbon-fiber structure using X-ray diffraction and electron microscopy has been developed. Average crystal-structure parameters are determined for samples of commercial polyacrylonitrile carbon fibers by X-ray diffractometry.
