The invention relates to a method for producing glass fibre reinforced plastics. Said method is characterised in that a size composition is applied to the glass fibre, the water is removed, irradiation is carried out by means of energy-rich radiation, and, in a second step, the sized glass fibre is incorporated into the plastic and thermal hardening is carried out at between 150 and 300 ~C, the polyisocyanate groups being released by deblocking.
L'invention concerne un procédé de production de matières plastiques renforcées par fibre de verre, qui se caractérise en ce que: on applique une composition d'enduit sur la fibre de verre; on élimine l'eau; on procède ensuite à une irradiation à l'aide d'un rayonnement riche en énergie; et, dans une seconde étape, on incorpore la fibre de verre à la matière plastique à qui l'on fait subir un durcissement thermique à une température comprise entre 150 et 300 ·C, avec libération des groupes polyisocyanate par déblocage.
