Abstract
The supermolecular structure of composites obtained by reinforcing an ultrahigh-molecular-weight polyethylene with C and Al2O3 nanofibers, Cu and SiO2 nanoparticles, and Al2O3 and AlO (OH) microparticles has been studied by means of X-ray diffraction analysis, infrared spectroscopy, and optical and electron microscopy. It is shown that the filler type (nano-, submicro-, or micro-) determines the character of the supermolecular structure, the evolution of friction transfer films, and the wear resistance of the composites.
