The invention relates to a method of making fiber reinforced molded articles and preforms for use in the manufacture of such molded articles which includes the steps of applying a layer of reinforcing fibers, preferably glass fibers, on a preform mold surface which has a configuration corresponding to at least a portion of the final molded article, coating the fibers with an ultrav- iolet light curable composition which contains a photohardenable material polymerizable under UV light and a polymerization photoinitiator, exposing the coated fibers to UV light to cure the composition, and removing the resulting preform from the pre- form mold surface. The preform is subsequently used by placing it and a deformable plastic material in a mold, where an article containing the plastic reinforced by the fibers is formed.
