Summary Properties of continuous mineral fibres and fibre reinforced composites compared to traditional fibreglass are analysed. These fibres have mechanical properties, comparable with S-fibreglass as far as E-modulus is concerned; a higher softening point than E- or Advantex glass and thermal stability up to 600°C. Introducing continuous mineral fibres into composite may cause a very great improvement in thermal and mechanical parameters. In unidirectional continuous mineral fibre reinforced composite on epoxy resin the data of E-modulus varies from 88 to 100 GPa. This makes them compatible with S-fibreglass or Aramid fibre reinforced composites. As a reinforced element of laminates continuous mineral fibres give the composite a more stable dielectric properties compared to E-glass fibres both under wet conditions and at temperatures up to 350°C.
