ABSTRACT:
A layer of a liquid composition containing an epoxide resin as the sole photopolymerizable component, a heat-activated curing agent for epoxide resins, and preferably a photopolymerization catalyst, is exposed to actinic radiation until the layer solidifies to form an essentially solid, continuous film due to photopolymerization of the epoxide resin through epoxide groups, the resin remaining, however, still thermosettable by virtue of residual epoxide groups. The film so formed is contacted with fibrous reinforcing material and caused to flow about the fibers, suitably by applying heat and pressure, to form a prepreg. When desired, e.g., after the prepreg has been formed into some desired configuration or layers of prepreg have been stacked, the assembly may be cured by further heating.
