Two kinds of composite materials reinforced by long unidirectional basalt fibres varying in the matrix type were
studied. The first type of matrix material was prepared by application of partial pyrolysis of polysiloxane preceramic
resin at a temperature of 650 °C. The second type of matrix material was utilised from cured only
polysiloxane and/or epoxy resin and served as reference materials. The advantages of partially pyrolysed
composites at elevated temperatures were described recently but the direct comparison with generally used
polymer-based composites was not explored deeply. Therefore, both representative materials were characterised
with the aim to determine similarities and differences in the fracture processes. The microstructural, elastic and
fracture properties were also examined. The fracture resistance was obtained in two typical directions, i.e. along
and across the fibres. The fractographic analysis together with fracture characteristics revealed strong and weak
aspects of both types of composite materials
