Abstract
A prepreg comprising a fibrous material contacting a polymerisable epoxide resin system, the epoxide resin system comprising at least one epoxide resin and a curing agent for the at least one epoxide resin, the curing agent comprising dicyandiamide having a particle size d(0.5) of from 1 to 15 microns in an amount of from 0,75K to less than 3.3K parts per hundred by weight based on the weight of the at least one epoxide resin wherein K = 287 / the mean epoxy equivalent weight, expressed in g/eq, of the at least one epoxide resin. The prepregs can be used for manufacturing wind turbine blades.
