"Selected mechanical properties of unidirectional composites with polysiloxane-derived matrix and continuous basalt fibres reinforcement are presented. A secial attention is devoted to the impact of long term explosition in hot air to the composite failure under flexural load. The investigated composites worsened their properties after treatment in air at elevated temperature (650-750\u00B0C). The originally non-catastrophic flexural failure changed to a brittle fracture, which was accompanied with a flexural strength decrease." . . "52" . "0862-5468" . . "21220" . "400698" .
