A method for producing resin-impregnated fibre composite material comprising glass and/ or mineral fibres, expanded microspheres and a curable resin.
<??>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 expanded before or after collecting. In a final treatment the material is pressed or formed, and the resin is fully cured. |
