In this work, selected solvent-free polysiloxane resins were investigated in terms of their application potential as environmentally friendly precursors of partially pyrolyzed composites with a hybrid polysiloxane/SiOC matrix reinforced with basalt fibres. Based on previous research, the solvent-free SiH/vinyl-functional resin was selected as a promising composite matrix precursor. In this work, the influence of pyrolysis temperature on the behaviour of new 1D hybrid composite materials was investigated. The microstructure of the composite and fibre-matrix bonding vary on their final pyrolysis temperature, which ranged from 420 degrees C to 750 degrees C. Similarly, a set of composites was prepared by the same technology using a conventional methylsiloxane resin containing 50% of solvent for comparison. Dimensional and mass changes were investigated during the pyrolysis process. The effect of microstructure development on the mechanical properties of the matrix and composite reinforced with the basalt fibres was determined. Maximum mechanical resistance was obtained for the composite pyrolyzed at 600 degrees C. The flexural strength of this hybrid composite reached the level of 650 MPa. The selected solvent-free SiH/vinyl-functional methyl-phenyl-siloxane resin was shown to give the prepared composites a high-temperature resistance above 600 degrees C. No significant difference in comparison with conventional precursor was observed during heat resistance experiments. The newly developed hybrid composite is, therefore, an environmentally friendly alternative for heat and fire-resistant applications.
