    Polyurethane (PU) matrix composites were prepared with various carbon fillers at different filler contents in order to investigate their structure, mechanical and microwave absorbing properties. As fillers, flat carbon microparticles, carbon microfibers and multiwalled carbon nanotubes (MWNT) were used. The microstructure of the composite was examined by scanning electron microscopy and transmission electron microscopy. Mechanical properties, namely universal hardness, plastic hardness, elastic modulus and creep were assessed by means of depth sensing indentation test. Mechanical properties of PU composite filled with different fillers were investigated and the composite always exhibited higher hardness, elastic modulus and creep resistance than un-filled PU. Influence of filler shape, content and dispersion was also investigated.

    Byly připraveny polyuretanové kompozity plněné rozdílnými uhlíkovými plnivy s cílem studovat jejich strukturu, mechanické a mikrovlné vlastnosti. Kompozity vykazovaly vyšší tvrdost, modul pružnosti a kreepovou odolnost než čistá PU matrice.
