 Full text | Abstract: In this contribution selected physical and mechanical properties of laboratory prepared basalt filaments and fibres drawn out from these are presented. The mechanical properties were investigated after tempering up to 800 °C. The ultimate strength distribution, torsional rigidity, deformation at break and sound wave spread velocity are mentioned. The thermal properties were investigated by TMA apparatus. The thermal expansion and compressive creep were measured. Analysis of a fibrous fragment evolved during the abrasion of basalt weave is presented. Basalt particles are too thick to be directly respirable, but their length/diameter ratio is higher than 3 and therefore the handling of basalt fibres must be carried out with care. |
