Abstract: The bodywork outer element of fiber reinforced plastic composite material for vehicles comprises a fiber reinforced plastic foam core (1) which after molding has an open-cell structure. An Independent claim is also included for a method for producing such an element. It involves production of a fiber reinforced plastic foam core with an open-cell structure after molding.

Abstract: Polyurethane foams having a density of less than 200 g/l are prepared by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms reactive with isocyanate groups, the polyisocyanates a) being aromatic di- or polyisocyanates and the compounds b) having at least two hydrogen atoms reactive with isocyanate groups containing at least one acrylate polyol.

Abstract: Polyol mixtures used for the production of energy-absorbing polyurethane foam comprise (b1) di- to octa-functional polyether-ols with OH numbers above 30 (including at least one with an OH number below 150) and more than 30 wt% ethylene oxide based on total alkylene oxide and (b2) polyether-ols with OH numbers above 30 based on propylene- and/or butylene oxide. A method for the production of energy-absorbing, semi-rigid polyurethane foam by reacting (a) optionally modified polyisocyanates with (b) a polyol mixture and optionally (c) other compounds with isocyanate-reactive hydrogen atoms, in presence of (d) water and/or other blowing agents, (e) catalysts and optionally (f) other additives etc. The polyol mixture (b) comprises at least (b1) di- to octa-functional polyether-ol(s) based on ethylene oxide (EO) and optionally propylene oxide (PO) and/or butylene oxide (BO), with an EO content of more than 30 wt% based on total alkylene oxide and an OH number of more than 30 mg KOH/g (including at least one polyether-ol (b1.1) with an OH number of less than 150), and (b2) polyether-ol(s) with an OH number of more than 30, based on PO and/or BO. An Independent claim is also included for energy-absorbing, semi-rigid polyurethane foam obtained by this method.
