Abstract:
1. An elastically deformable composite material suitable to be processed further into sheet-like abrasive products, consisting of a sheet-like supporting base made of a fibrous construction or a laminate comprising at least one fibrous web and at least one laid scrim or is laminate comprising a plurality of fibrous webs or a plurality of laid scrims, wherein the elastically deformable composite material has a grammage of 100 to 1600 g/m 2 and a thickness between 0.15 and 2.5 mm, characterized in that the supporting base comprises at least one layer of laid fibers selected from inorganic fibers and organic synthetic fibers, if necessary mixed with natural fibers and that the supporting base is coated or impregnated with a prepolymer material, said prepolymer material acquiring thermosetting properties when thermally post-cured, wherein the prepolymer material was applied onto the supporting base in the form of a resin, a dispersion or a suspension and then dried, but not thermally post-cured such that it is present in a solidified status, but not in its fully cured status where it is a thermoset.
