More Information
Summary:The present disclosure is directed to a process for forming a reinforced ultraviolet (UV) radiation-curable composite. The composite may be formed by applying reinforcing layers and resin layers to a substrate. The resin composition may include an aliphatic urethane acrylate oligomer, a polyfunctional acrylate monomer, and a photoinitiator. The composite formed on the substrate may be exposed to UV radiation to cure the composite on the substrate. The composite may be characterized in that it is cured within 10 minutes of exposure to UV radiation and does not exhibit oxygen inhibition effects, such as, for example, surface tack. The reinforced UV-curable composite may find utility, for example, as a rapid field repair patch in aerospace applications, among others.
