Abstract:

An effort was undertaken to thoroughly characterize an adhesive, EA 9394 Hysol. The characterization was directed toward repair applications for aluminum andor composite structures. The study includes data on the effects of time, pressure, and temperature on adhesive tensile lap shear properties. The mechanical properties measured included tensile lap shear, floating roller peel, and flatwise tension and climbing drum peel on adhesively bonded honeycomb structures. The mechanical properties were measured at reduced, room, and elevated temperatures and after humidity aging. Effects of storage time and temperature, cure temperature, primed adherends, bondline thickness, and batch- to-batch variation were also investigated. Several physical and chemical characteristics were investigated to measure the effects of storage conditions and to aid in selection of cure conditions.
