The present invention relates to a surface tension modifier for use in liquid curable composite materials, wherein the modifier is the reaction product between a polyol and an organo-functional silane. The present invention also relates to a method for producing a fibre reinforced composite material, and a fibre reinforced composite material when produced by the method. The method comprises the steps of contacting a plurality of reinforcing fibres with a curable resin mixture and curing the curable resin mixture, wherein the curable resin mixture comprises a curable resin and a predetermined quantity of the surface tension modifier of the invention. The present invention further relates to a method of improving wettability of a resin and use of the surface tension modifier of the invention.
