Abstract
The invention relates to a method for producing a fibre composite material, which comprises glass- and/or mineral fibres, expanded microspheres and a curable resin. In the method a melt of glass or mineral is prepared and the melt is converted to discrete fibres by means of nozzles. A water-based solution or dispersion of a thermosetting resin is applied to the fibres, which solution or dispersion contains microspheres. The obtained material is collected and the microspheres are brought to expand before or after the collecting. The invention also relates to a final treatment of the obtained material in which the material is pressed or formed and brought to set to the C-stage. The invention also relates to the products obtained by the method.
