The aim of this thesis is to investigate the feasibihty of manufacturing polyurethane glass fibre laminates with vacuum infusion. Thermoset resins classically used for infusion have been polyesters, vinyl esters and epoxies due to their long pot life. Polyurethanes have faster reaction kinetics and therefore the cycle time could be reduced. Additionally, it is expected that polyurethanes bring improved fatigue and impact resistance properties which would enable a re-design of the structures,
reducing its thickness. Therefore, the manufacturing costs of large structures, such as wind turbine blades, could be reduced...
