A composition for the production of a prepreg for the manufacture of thermoset composite laminates, a method for the production of a prepreg, the prepreg, and a thermoset glass fibre reinforced composite laminate manufactured by curing the prepreg. The composition comprises unsaturated polyesters or vinylesters (A, B), a catalyst (C), a thickening agent (D), and a crosslinking initiator (E), a first component (A) of the unsaturated polyesters or vinylesters comprising reactive groups that react with the thickening agent (D), and a second component (B) of the unsaturated polyesters or vinylesters not comprising any groups that react with the thickening agent (D), the composition also comprising a polyether polyol (F). |
