| titleOfInvention | Compact polyurethane |
| abstract | The present invention relates to a compact polyurethane having a density of ≥ 850 g/l, which is obtained or can be obtained by reaction of at least the components: i) polyisocyanate composition; ii) polyol composition, comprising at least one polyether polyol (ii.1), which is obtained or can be obtained by reaction of ii.1.1) a polyol starter with a functionality of 3 to 6 with ii.1.2) propylene oxide and/or butylene oxide, in the presence of a boron-based fluorine-containing Lewis acid catalyst (ii.1.3), wherein the polyether polyol (ii.1) has an equivalent molecular weight of 50 to 150 g/mol, ii.1.4) optionally further auxiliary materials and/or additives. The invention further relates to a method for producing a compact polyurethane of this type and to compact polyurethanes which are or can be obtained by this method. The invention additionally relates to the use of a compact polyurethane of this type having a density of ≥ 850 g/l for the production of a fibre-reinforced composite material. The invention likewise relates to a corresponding fibre-reinforced composite material and a method for producing a fibre-reinforced composite material of this type. |
