Description
Summary:Interpenetrating polymer network (IPN) materials possess unique properties that can be exploited for multicomponent composite armor systems, including toughness and thermal stability. E-beam curing of composites and adhesives offers advantages, such as reduced cure shrinkages, over traditional autoclave processing by curing multiple resins through the thickness for thick-section composites in a single step. Because of the complexity and thickness of composite integral armor structures, e-beam curing is an attractive processing method for Future Combat System applications, and the development of these new resins permits this approach. This research seeks to discern the differences in viscoelastic behavior between traditional thermal and e-beam curing in IPN resins, as these viscoelastic characteristics may prove important for composite integral armor applications.
