Abstract: Flat composite (I) 1-20 mm thick, with density 0.1-1.6g/cub.cm., flexural strength (DIN 53423) 5-60 Pa, E modulus in flexure (DIN 53457) 500-6000 Pa, impact strength (DIN 53453) 5-50 kJ/sq.m., and heat flexural resistance temp. (DIN 53424) 110-250 deg.C., comprising a cellular polyurethane (PU) thermoset having embedded 51-80 wt.%, on total wt., of a fibre-contg. flat object (II). Prodn. of (I) by (a) laying a (II) in open mould and spraying with amt. of foamable PU thermosetting mixt. having viscosity 200-2000mPa-s at 20 deg.C and gel time 15-240 seconds at 80 deg.C such that wt. ratio of (II) to foamable PU mixt. is 51-80:49-20, or laying analogously obtd. (II) sprayed with foamable PU mixt. in open mould; (b) closing mould; (c) alloying PU mixt. to foam and harden in closed mould.
