Résumé :	For the first time ever, polyurethane (PU) prepregs suitable for storage can be both produced and processed on an industrial scale. These materials offer a cost-effective alternative to epoxy prepregs as they deliver components with comparable mechanical properties at significantly lower production costs.
Note de contenu :	- Two-stage curing reaction with polyurethane - Faster reaction, shorter cycle times - Higher glass transition temperatue makes annealing unnecessary - Practical example - leaf springs with 25% lower manufacturing costs - Potential for SMC - FIGURES : 1. The injection box developed for the new polyurethane casting resin system enables reproducible, controlled reinforcing fibre impregnation without air bubbles - 2. The new polyurethane casting resin system has significantly lower exothermic reaction than corresponding epoxy systems - 3. Prepreg pressing system
