Abstract: In this study, various technical ceramics in the form
of nanostructures, known for their exceptional mechanical properties and
thermal resistance, were analysed as potential reinforcement of a
polymer matrix system. A combined, hybrid composite matrix was
considered, consisting of epoxy resin and polyvinyl butyral. The
following nanostructures were incorporated into the polymer matrix by
ultrasonication and solvent-casting technique: B4C, TiB2, CNT and
INT-WS2. Polymer composites were prepared by solvent-casting of neat
hybrid polymer matrix and polymer matrix reinforcing with each chosen
individual nanostructure from a temporary solvent – ethanol. The
characterisation of the obtained polymer composite samples encompassed
Fourier transform infrared spectroscopy analysis, differential scanning
calorimetry, tensile test, hardness measurement and examination of
resistance to cavitation wear.
Keywords: technical ceramics, nanomaterials, composite
materials, polymers, fibre-reinforced polymers, mechanical properties,
cavitation wear.
