Abstract : Composite film supported by a nylon fabric carrier consisting of a modified epoxy adhesive on one side of the carrier and a nitrile elastomer on the other side was evaluated as adhesive in this study. Examination revealed numerous voids in the cured bond. These voids appear to roiginate from air entrapped in the adhesive during its manufacture and/or from volatiles evolved furing the cure These voids were also shown to be interconnected by the filaments of the cloth used as the carrier of the adhesive resin. Efforts have been made to synthesize adheisve resins with reduced brittleness and greater moisture resistance. (Author, modified-PL)
