Abstract : Resin systems that are curable at reasonable rates at ambient temperature, or at slightly elevated temperatures, are needed for temporary repair of composite structures on damaged airframes. However, efforts to date have not been successful in yielding properties useful at temperatures higher than the cure temperature. The committee reviewed the state of the art and recommended a number of approaches for supported research. These include preordered reactions, acrylate esters, reactive solvents, waveguide curing, epoxy resins, secondary ring closing reactions, donor-acceptor complexes, and the use of fillers, in conjunction with these approaches.
