Abstract

The article presents the results of the experimental studies of the structural transformations of a powder mixture of ultra-high molecular weight polyethylene and 80 wt.% (45 vol.%) of the nanostructured composite B4C/W treated in a high-energy ball planetary mill that are studied by the methods of X-ray diffraction, scanning electron microscopy and Fourier-IR spectroscopy. It is shown that the polymer composite particles of a flaky shape and the size of 160–400 μm with a uniform distribution in them of boron carbide and tungsten particles with the size of 1–5  μm and 0.1–0.2 μm respectively are formed during the process of mechanical activation (MA), while the oxidative destruction of polymer is not detected. The main results of the interaction of the polymer matrix and dispersed filler powders with MA are the processes of breaking of intramolecular bonds, cross-linking of polymer molecules, as well as mechanical dispersion of particles.
