The present invention relates to a method for producing a fibre-reinforced, transparent composite material (10), comprising the following steps: a) providing a material matrix melt and b) producing reinforcing fibres (14), step b) of the method comprising the steps of b1) providing a mixture having a silicon source and a carbon source, the silicon source and the carbon source being present together in particles of a granulated solid; b2) treating the mixture provided in step a) of the method at a temperature in a range from ≥1400° C. to ≤2000° C., more particularly in a range from ≥1650° C. to ≤1850° C.; thereby producing reinforcing fibres (14), the method comprising the further steps of c) introducing the reinforcing fibres (14) into the material melt; and d) optionally cooling the material melt to form a transparent composite material (10). A method of this kind allows a composite material to be produced that is able to unite high transparency with outstanding reinforcing qualities.
