Evaluation of properties of pyrolysed resins
Halasová, M. ; Chlup, Zdeněk ; Strachota, Adam ; Černý, Martin ; Dlouhý, Ivo
The presented work describes mechanical properties of materials prepared by pyrolysis of polysiloxane resins. The polymeric precursors had different chemical composition. Materials under investigation are predetermined as a matrix for high temperature resistant long fibre composites. An instrumented hardness tester was employed for materials characterisation. The Vickers hardness, Martens hardness and indentation elastic modulus were the key parameters determined from the load-indentation depth curves. Influence of the mechanical properties on the ratio of T and D was established. Indents were observed by using confocal laser microscope.
