Abstract of the Disclosure The invention relates to a novel fibre composite material and a method for producing the 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 thermo- setting 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 the collecting. The invention also relates to a treat- ment of the obtained material in which the material is pressed or formed and set to the C-stage and the product obtained therefrom, The novel pressed or formed product may be produced as a comparatively thick sheet rather than from several separate layers of impregnated web-form material in accordance with the closest art. The material has reduced brittleness and creep and increased stiffness, impact strength and resistance to climate factors, fire and chemicals.
