Abstract : Several commercially available resins designed to be cured with ultraviolet radiation were evaluated with respect to their potential for use in the field repair of composite materials. Thermal and mechanical properties of cured resins were evaluated by DSC and TBA techniques. Some cured resins exhibited physical properties which may be suitable for repair application. None of the tested materials was able to cure when impregnated in woven graphite cloth which strongly attenuates the curing radiation. This prevented the use of fiber optics to cure these systems. Keywords: UV curing; Fiber optics; Low energy curing; Field repair; Composite materials; Curing.
