Abstract
A Cooperative Research and Development Agreement (CRADA) sponsored by the Department of Energy Office of Science, NASA Langley Research Center, U.S. Air Force Research Laboratory, U.S. Army Research Laboratory, and several industrial partners has developed or improved several toughened cationic epoxy resins cured by electron beam irradiation. These resin systems have mechanical, thermal, and physical properties that are significantly better than earlier electron beam curable resins, and are comparable to many thermally cured, high performance, toughened and untoughened epoxies. Neat resin test results and comparative data on fracture toughness properties, tensile properties, thermal properties, water absorption values, cured resin densities and resin viscosities are discussed.
