Abstract (in english)
   The presented work describes mechanical properties of materials prepared by the pyrolysis of polysiloxane resins. The polymeric precursors have different chemical composition. Materials under investigation are predetermined for high temperature resistant applications usually in composite form, i.e. accompanied by some reinforcement. Instrumented hardness tests were employed for material characterisation. The Vickers hardness, Martens hardness and indentation elastic modulus were the key parameters, determined either from the standard optical technique or load-indentation depth curves. The influence of mechanical properties on the monomers ratio was established. The exposition to the temperature between 1200 ◦C and 1500 ◦C in air was applied to observe damage caused by these severe conditions.
